Twitter is nothing short of a phenomenon. At the very least, it connects people to each other through a rich and active exchange of ideas, thoughts, observations, and vision in one, highly conducive ecosystem (known as the Twitterverse). The social fibers that weave together this unique micromedia network is strengthened by the expertise, respect, trust, admiration, and commonalities. These fabrics bind the people who breathe life and personality into the global community as well as fueling the disparate micro communities that ultimately extend across the Long Tail.
Of all of the social tools and services that are pervasive throughout our digital society, only a select few communities can boast the pseudo fanatical conviction that Twitter‘s users unanimously possess.
Twitter is quickly gaining momentum, support and market inertia and is on direct path to mainstream awareness. Compete.com numbers show that roughly 2.5 million people visit Twitter.com each month, growing at about 250,000 – 500,000 users per month and up over 440% since this time last year. Just as a comparison Facebook receives about 41 million unique visitors per month.
Twitter is not only embraced and cherished by the people who rely on it for expression, insight, news, and communication, it is also the darling of the developer community. Almost every single day, a passionate developer, b2b or b2c application company, or tech enthusiast will develop a new tool, service, or solution to make Twitter a more personalized, professional, streamlined, effective, and/or fun experience.
If you live in the world of socialized marketing, communications, relationships, communities, research, service, digital anthropology, fundraising, publicity, product development, publishing, events, online reputation management (ORM) or simply seeking to increase your proficiency and efficiency on Twitter, there is surely no shortage of tools and applications that can help you.
I created this snapshot guide to help you extend the reach and the efficacy of Twitter for your personal brand as well as the brand you represent. This is the first part of a multi-part series. If you’d like me to review and include additional tools and services, please share them in the comments and I’ll integrate into the next rev.

The results are viewable by week, month, and quarter and the service will also predict the future volume of followers based on the average growth/loss over time.

TwitterFriends is one of the most compelling analytical tools for identifying relevant conversationalists, revealing conversation patterns, and visualizing material conversation networks, by Twitter ID. The services aims to map the “relevant net” for any given user, which is incredibly valuable to any communications or service professional identifying influential voices and associated social graphs. For example, stats list to whom you (or any username) reply most often and those who reply back. The system determines a Conversation Quotient (CQ) that attaches a metric to the volume of tweets that include @ replies. For reference, the average CQ is 25.4%. The reports also provide the size of the relevant net (those you reply to or receive replies more than once in the last 30 days) outgoing and incoming, number of fans, loyalty, Twitter Rank, ratio of outgoing/incoming contacts, the follow cost, the conversational rank (number of public conversations with users), number of replies, a Retweet Quotient, Link Quotient, among many others.

It essentially turns your Web browser into a simple, visual social media dashboard. While there are many third-party tools for Twitter, PeopleBrowsr brings the best features from all of the popular add-on services into one solution – without requiring a download or a browser plug-in. More on PR 2.0.
CoTweet is a platform that helps companies listen to and communicate with customers and influencers on Twitter. Like Splitweet, businesses can manage multiple accounts in one dashboard. In addition to PeopleBrowsr, CoTweet is perhaps among the first dedicated Social CRM solutions designed specifically for businesses. It allows for multiple simultaneous users to monitor conversations related to the brand, assign action to other treammates on the community management team, schedule messages, and reply from different accounts – all from one window.
Splitweet is a multi-account management dashboard for corporate users and brand managers. Designed for power users, it provides seamless management, monitoring and communicating across several twitter accounts simultaneously – all from one place.
Power Twitter is a powerful plug-in for FireFox that moves many disparate services and capabilities into one central location – right in your browser. This is almost a complete Twitter experience for the general and even power use, one that Twitter itself should provide. First, Power Twitter provides an at-a-glance Twitter history view for every person in your timeline. Second, search functionality is built in, so that keywords and hashtags are immediately viewable without opening a seperate window. And, @replies functions as it should. It reveals not only those tweets that begin with @yourusername, but now also include every tweet with @yourusername, regardless of where it’s positioning in the message. Similar to TweetTree, content linked to in sites such as Flickr, YouTube, and TwitPic appear in the timeline – again saving you time from having to jump outside of Twitter. Overall, Power Twitter is a seamless experience. Install it, hit Twitter.com as you normally would, and you’ll notice the new and improved capabilities.
Gridjit is a social portal that lets you view your web universe in a more visually rich way. It becomes your hub for tracking conversations, interesting people and those they @ frequently, and also provides a central location to post and share.

GroupTweet is similar to Yammer, except it’s within Twitter. Workgroups, extended networks, communities, and anyone who wants to broadcast and share private tweets to a specific group can do so for free using this unique and helpful service.
Tweet Later allows you to schedule tweets for a particular time and day. It also allows you to auto-follow those who follow your account and provides an auto-welcome feature to send a custom message to new followers via DM or in the public timeline.
Tweetbeep is the Google Alerts for Twitter and is a “listener’s” dream service. It allows you to monitor conversations that mention you, your brand, related or competitive products, as well as links to your website or blog, even if they use a shortened URL, such as tinyurl.com. You’re alerted as your keywords appear, reducing the need to manualy search for them.
Twilert is also an “alert” for Twitter that monitors Twitter for your keywords and sends them to you via email on a daily, weekly, or monthly basis. Having these emails trip as keywords appear would be ideal for any brand manager.
TwitterFeed connects your blog to Twitter and automatically feeds posts into the timeline with each new update.
Twiffid shows the headlines of the Websites your Twitter friends have listed in their profiles to see what they’re linking to or blogging about.
TwitThis is really a potentially powerful and game-changing service, if it gets traction. If you’ve ever visited a site or blog and have seen or used the “share this” or “email this” feature, TwitThis is similar in concept. Essentially, it grabs the url of the page you’re on, compacts it into a TinyURL, and then allows you to add some thoughts to directly post to Twitter from the page you’re visiting.
Diigo.com offers one of the most feature-rich and robust social bookmarking / web annotation services on the web today. Via Diigo’s “Twitter-this” feature, you can easily share interesting websites or content on Twitter with a shortened URL – from the page you’re visiting. It also allows you to easily add highlights and sticky notes to any webpage, and then share the annotated page with your Twitter followers. They will just see an ordinary link in the twitter message; but when click the link, they can also see your highlights and sticky notes right on the page.
Tweetree is a new service that attempts to thread related conversations in Twitter. Considered an alternative for those who read and post updates through Twitter.com, Tweetree also allows people to share content directly in the timeline. By simply including a link from YouTube, Flickr, TwitPic, FriendFeed, Seesmic, Qik, Lala, or Blip.fm, Tweetree embeds the content inline for others to enjoy without leaving the service.
OutTwit might just be the tool that bridges Twitter to the enterprise. More people use Outlook in business than any other email client. Now you can update Twitter and tap into the stream directly from Outlook. If you’re a brand ma
nager, community manager, or communications professional, you can establish search criteria for keywords and channel the results into dedicated folders in Outlook. You can also categorize and archive tweets through a seamless folder creation and storing option.
TwitterMail allows you to update Twitter via email. Once you log in, the system provide you with a dedicated email account, such as firstname.lastname@example.org. When you send an email to that address, it will automatically post a tweet for you. The service also sends email directly to you as you receive @ replies, which is ideal for brand and community managers. TwitterMail provides the ability to read your timeline in email by addressing a message with “friends” in the subject line. The service will send the last 20 updates immediately. If 140 characters won’t work for your individual tweets, type the full context of what you’d like to share and TwitterMail will link the tweet back to the full posting for all to enjoy. And, through TwitterMail you can schedule tweets for publishing at a later date/time.
TWPLY is new service that tracks personal @replies and sends them to your designated email inbox. Seems simple enough and may be ideal for those high volume personal and corporate brands that need to actively monitor inbound tweets without having to stay connected directly to Twitter, Twitter Search, or a third-party service.
TWPLY is highly regarded as a spam app and raises questions as to the value of the service overall. On the heels of its rise and fall, we learn about Replies by Twitapps, a more elegant solution for receiving @replies on Twitter in your inbox. It delivers your updates on an hourly basis or when your replies reach a threshold of 25 tweets (whichever is first). Again, this is ideal for any brand manager, community manager, or communications professional, tracking important usernames on Twitter.
EasyTweets is a solution for pre-scheduling tweets. Brand managers and customer service and communications professionals can also manage multiple Twitter accounts, check replies, and track new followers from one central hub.
Whoshouldifollow.com makes it easy to find relevant, like-minded friends as well as friends of friends based on keyword and validated networks.
Twubble can help expand your Twitter network. It searches your friend graph and introduces and recommends new people who you may want to follow.
Twellow, a service of WebProNews, is an exceptional service for finding people who matter to your business or industry, by category. You can search keywords or browser through common categories to find the voices you deem as worthy following and/or connecting with on Twitter or other social networks. You can also claim your Twitter ID to further customize your individual profile with a short bio, extended bio, links to other profiles popular social networks such Facebook, LinkedIn, Delicious, Flickr, FriendFeed, etc.
Twitter Karma is an interesting and also very useful tool for visually identifying those whom you follow, who do or do not follow you, and the relationships that are mutual. In one dashboard, you can determine whom you should also follow as a token of reciprocity or a simple matter of missing an important new follower/s and also whom you can contact to also return the favor. It also makes it simple to individually check those to follow or unfollow and also provides the ability to bulk follow, unfollow and block.
Like Twitter Karma, FriendOrFollow provides a simple and quick solution to find out who you’re following that’s not following you and who’s following you that you’re not following back.
TweetWheel visually presents your social graph, who’s following you and who you are in turn following. It is a helpful solution for identifying who you may or may not need to follow, as well as view the friends you share in common.
Even though Twitter features a directory search engine by name and email address, TwitDir always seem to find everyone, even when Twitter misses a contact. I use TwitDir when I’m looking to discover whether a particular contact or someone I’m trying to connect with is using twitter. Alternatively, you can use Google or Yahoo search and type “PERSON NAME” (in quotes) and the word twitter (outside of the quotes) in the search box to find the username. See example.
Tweet Pro is a paid service that allows you to create a solid network based on keywords and interests. The software allows you to locate specific Twitter users to enable mass, but focused following to generate a highly targeted account for your business/brand.
DoesFollow is as simple as that. If you want to know if USERNAME follows USERNAME quickly and easily, this is your
Tweet 2 Tweet
Tweet2Tweet provides you with the ability to view a history @replies between to Twitter users, which can be helpful for learning and understanding perspective and context.
Qwitter will send an email to you when someone unfollows you and will link the action to the most recent tweet that you posted. Through a series of experimental tweets, Qwitter is a humbling and instantaneous solution for honing your updates to better match what your friends and followers hope to see or not see.
Twitter Twerp Scan
Twerp Scan checks the number of followers of everyone on your contact list, the number of people they are following, and the ratio between those. If the person is following more than (n) people (can be customized), and has a Following-to-Followers ratio higher than 1:(m) (can be customized), you’ll be notified by a link. Even if you have no use for that, you might find Twerp Scan a helpfultool for keeping an eye on your growing list of friends and followers.
TweepSearch is the first search engine that allows anyone to search and discover relevant Twitter bios and location information using keywords. It’s ideal for learning more about those following any given username as well. For example, type @username and you can puruse through individual followers of @username and their corresponding Twitter bios.
Headup is a semantic desktop app that boosts and connects the social Web experience. When applied to Twitter, it places a Headup underline/icon next to user names, which when clicked, allows you to dive deeper into their online profile. Headup scours the Web and prepares an instant directory of social profiles and links to their persona and other online activity. Download Headup here.
Mr. Tweet is your personal networking assistant on Twitter. It helps you easily build meaningful relationships by looking through your network and tweets. Mr. Tweet will then suggest new and relevant tweeps and existing followers you should also follow. “He” also provides usage statistics that help you improve your engagement level on Twitter.
TwitterSnooze is a very welcome solution. There are many people that I follow whose tweets I usually enjoy reading. However, sometimes, those tweets can be obscure, irrelevant, loud, or unnecessarily narcissistic. Or, every now and then, a good friend will attend a conference, session, event or workshop that I don’t care to endure virtually. TwitterSnooze provides the ability to “snooze” certain friends for a pre-determined period of time. If you’re daring, you can also publicly tweet that you’re snoozing someone.
Twalala adds a mute button to Twitter allowing you to focus your stream as necessary without completely unfollowing someone.
Developed by Brooks Bennet, TweetChat is a service that introduces the ability to focus on specific conversations or topics. Using a “room” metaphor, users simply type in a hashtag (#name or #id) or a keyword related to brand, news, topic, etc., to specifically identify and channel all tweets related to that conversation. You can read and respond directly from TweetChat.com, but requires login using your Twitter ID and password.
My Tweeple is a Twitter follower/following manager that provides a one-stop dashboard for who you’re following and who, in turn, is following you. The service allows you, with a single click, to follow, unfollow, or blog people (or tweeple).

Before Summize, now the official Twitter Search engine, Twemes and #hashtags provided the ability to index conversations based on keywords, groups, topics or tags also known as #hashtags. These Twitter memes can now be followed outside of the public timeline through a focused and dedicated stream.
Tweet Scan, like Summize (Twitter Search), is a search engine for Twitter. Both services provide the ability
to search keywords, company/product/competitors names, users, etc. The services also feature the hottest search trends at that particular moment. I have noticed that in some cases, one or the other, consistently provides results that the other missed. Note, by clicking “Replies” in Twitter, you’re only seeing tweets that start with @yourname. These search engines also track users as well as important and relevant keywords – as they appear.
@MicroPR is the brainchild of Stowe Boyd and Brian Solis (with the help of Chris Peri.) It connects journalists, bloggers, analysts, and other influencers to PR. If you’re in PR, communications, blogger relations, community management, analyst relations, make sure to follow @microPR on Twitter.

twInfluence allows you to measure Twitter influencers, not just by followers, but also by reach, velocity, social capital and centralization. It also publicly ranks the top 50 influencers in each category. This is an important tool for identifying the tastemakers that you don’t already know in the Twitterverse.
Twitority is a new service that that facilitates the search and sorting of keywords in Twitter by authority, or in less controversial terms, popularity. At the moment, authority is measured by followers, but perhaps, Twitority will eventually create an algorithm similar to Twinfluence in order to more accurately measure influence. Twitority is a simple, yet helpful service that will help brand managers, community managers, and communications and customer service professionals tier research and response strategies and programs. It’s also helpful to identify and measure potential opportunities and new trends based on the weighted discussions surrounding relevant topics. Searches can be sorted by any, little, or more authority.
