It used to be much nicer to use, back when Twitter acquired it. (It was called Tweetie then.) The notifications were better, the mechanics of doing things like following conversations or refreshing a conversation were simpler, filtering options were better, etc. And I don't think it had a prominent spot in the dock... IIRC its icon was mainly in the menu bar. It's been a while since I used tweetie or twitter, though, for very much at all. I'm really sorry to see it go away more because it used to be a nice UI playground for a talented developer than because of any recent experience with it.
