bTT is a FriendFeed-Twitter combined downloadable module that runs independently from the sobees platform. The module allows you to integrate comments/likes directly into the main flow, show/hide all comments, post directly to Twitter and Friendfeed and filter streams by service.
For the Twitter service, bTT shows the difference between where the updates are coming from by highlighting Twitter updates in sky blue, while Twitter updates through Friendfeed follow the standard color scheme, black.
bTT and sobees are built in WPF and runs on Windows Vista / XP. Both require .NET 3.5.
