From the developer:
Tweedie is a new kind of Twitter client for Mac.
Tweedie treats all tweets as just one big stream of tweets, then lets the user organize them based on hashtag, @names, urls, categories, and media types. With simple drag-and-drop actions, you can easily create custom filters to group and manage your tweets.
You may want to check out more software for Mac, such as Showit, Facebook for Adobe AIR or Cortex, which might be related to Tweedie.
