I saw Tweego.net as a bookmark in someone's screenie and have been using it ever since. You really need to make the credits (YOU) present in the app. It's really great!

My only wish for it is, that could Tweetgo somehow remember my login (forever)? It always asks me to log in and very often this results in an "Twitter is at overcapacity" as I try to log in. :/

But thanks a tonne for this app, the UI is perfect!
