Paul Haddad updates you about an update:
A lot of our Tweetbot for Mac Alpha users have worried about what’s going to happen to them now that the Alpha has been pulled. A few folks have suggested that we release a new version but without the ability to add any new accounts, we thought it was a good idea and have done that.
Good workaround on the part of Tapbots. Also, there are a bunch of nice updates that go with this beta. I’ve been switching between Tweetbot and Twitterrific for Mac for a while now, and they’re both very strong apps.
