Hey all

I have used everything from Witter to Contacts, unfortunately the latest Witter build has gone a bit pants, TweeGo is not there yet.

The best so far is www.tweetgo.net, a web app but looks amazing and is quick, no geo local or twitpic though

Next is Hahlo.com, amazing implementation, another web app also, features inline replys, inline pics and video in the tweets themselves and geolocal, but just not have snazzy WP7 looking at Tweetgo.net
