Twitter Apps

TweetWire - “grabs the freshest links posted to Twitter around the clock”. Using Tweetscan, Yahoo! Pipes and human filters. So far there are four categories of news: election 2008, celebrity, tech and sports.

Intwition - tracks links on Twitter, enter a domain and Intwition provides information on the pages that have been linked to, how many times and by who. Not sure how comprehensive this is, but it could be really great. Also includes a leaderboard and a “new item finder” or what’s popular now page.

Twitt(url)y - tracking popular links on Twitter. “It operates similar to Digg where people vote on an item and it gets displayed higher up the home page, but more closely to PageRank where basically every person that links to the same final url, is considered a vote for that URL.” Not terribly impressive as yet.

Alpha Twitter - lists top shared links on Twitter and the people who shared them.

twitigg - digg for Twitter, popular stories submitted to Twitter.

twitio.us - “Twitter + del.icio.us”. Add the Twitthat bookmarklet and post links and comment to Twitter as you browse.

Twitter Linkr - monitor links on Twitter.

Twitter Buzz - view the most popular Twitter links for the last day.

Tweetl - shorten URLs.

Tweetburner - shorten links and track what happens to them.

Twittes - nice site monitoring links about Twitter posted in Twitter. You could spend a lot of time here.
