Twittereeze is a SIMBL (Smart InputManager Bundle Loader) extension for Twitterrific (freeware), a Mac OS X client for the Twitter service. Twittereeze aims to improve Twitterrific's user experience in small ways.

While Twitterrific itself is a nice little app to send and receive 'tweets', i.e. change your own status and stay up-to-date on that of others, I primarily use Twitter in a similar manner to an IM network's status message. Thanks to AppleScript, the status messages of iChat (AIM/.mac/ICQ, Jabber/Google Talk/LiveJournal), Skype and Adium (many, many protocols) can be changed through a simple API. With Twittereeze enabled, any status that Twitterrific sends to Twitter as a 'tweet' automatically becomes your status on those three applications as well, provided you have them running.
