Whats the difference between Web Links and Share Links?
Web links are what Tweet This has always used. They take the form http://twitter.com/home/?status=Your+message and will display “via web” when tweeted. Share links are like http://bit.ly/asEAtj (long URL) and use the same API as the official Tweet button, but as a regular link instead of a JavaScript popup. They use Twitter’s official URL shortener, T.co, allow you to specify up to two related users to be suggested after the tweet is made, and will display “via Tweet Button” when tweeted.
