20 Twitter Applications You Need to Know About

With more than 50 million users visiting Twitter in July, the microblogging service has become quite the destination for short updates about what we're doing in the moment. In addition to being a hot destination, Twitter has fostered a whole new ecosystem of real-time communication. Countless applications are popping up to take advantage of the Twitter API to help make their Web services viral. Many of these services enhance the Twitter experience.
TweetMeme
TweetMeme is a service that aggregates all the popular links on Twitter to determine which links are popular. TweetMeme also makes the retweet button, which is for content publishers who want to invite their audience to tweet their content on Twitter. The button shows a live count of the number of times your Web page or blog post has been tweeted.
TweetMeNews
Hailing from nobosh labs, TweetMeNews tweets users' personalized news based on their interests. Nobosh Labs' reason for creating TweetMeNews captures the Twitter zeitgeist in a nutshell: "Nobosh has been developing a news personalization engine for over a year. As time went on Twitter exploded! Since that explosion the world has seen a convergence of information on Twitter, reducing the need to visit other sites."
TweetDeck
A super popular application, TweetDeck is a real-time Web browser that connects users to their contacts across Twitter, Facebook and other social sites. TweetDeck also boasts a version of its social application for the iPhone that geeks are giddy over.
TweetVite
TweetVite is pretty much what you'd think it would be from the name: Use it to create invitations for events you're hosting or to find local Tweetups.
TwitVid
Again, as you'd guess from the name, TwitVid lets users upload and tweet videos on Twitter.
Vidly
Another app for sharing video on Twitter, Vidly recently changed its name from Twitvid.io.
Twitoaster

Tweet From Above/Tweet From Below
Tweet From Above and Tweet From Below let users send heavenly and hellish tweets anonymously.
TwitPic
You get one guess as to what TwitPic lets you do. You would not be wrong if you said it lets you share photos in tweets.

Twitbin is a Firefox extension that allows you to keep up with all of your Twitter conversations right from your browser sidebar.
Twitterholic
Twitterholic scans the Twitter public timeline for new twits to tweet and calculates individual statistics for each Twitter user.

Twtpoll
Another Twitter tool whose name spoils any nomenclature mystery, Twtpoll is a feedback tool that lets users create and distribute polls/surveys on Twitter, Facebook, FriendFeed or any other social media site.
Retweetist
Retweetist tracks retweets, or messages tweeted on Twitter that repeat information previously tweeted by another user.
Tweepler
Tweepler lets users separate the wheat from the chaff, helping users decide if they want to follow new followers or not.

TweetScan sends users e-mail when their keywords are mentioned on Twitter.
Tweetburner
For those who can't get enough of following the data flow on the links they share on Twitter, here's Tweetburner.
Twittervision
This is so cool: See who is posting what from where in real time with Twittervision, as a sort of mashup of Twitter and Google Maps.
Twibs
Twibs helps users find businesses on Twitter. Great promotional tool.
Twitdom
Finding Twitter apps can be a royal pain, particularly because so many are built by some programming shops, or even just lone wolf programmers. Twitdom is a Twitter apps database that provides a "consolidated view of all the applications developed for the Twitter ecosystem."
