Shawn wrote a really nice review of Tapbots’ new Twitter client: Tweetbot. It just hit the U.S. app store last night and is overwhelmingly nerd popular. I have a mixed set of feelings about the app and haven’t used it enough to say for sure whether it is right for me or not. There is a lot of UI chrome going on and no real “must have” feature — I put it in my dock in place of the Twitter app and we will see if and how long it stays there.
