Tweetdeck was created in 2008 to be a better interface to Twitter, back when Twitter had an open API and more fun. Twitter acquired it in 2011 and then... did absolutely nothing with it. I checked it out today, and it looks and feels like it did back then.
This is actually great! It runs very snappily on my #PinebookPro and has few UX annoyances. I don't post much on Twitter, but I still follow it, and it works very well for that.
