We just pushed out a WordTwit upgrade to 2.4. There are two major changes in this release.
1) Asynchronous Tweets - if a Tweet fails, it will be pushed out at a later time asynchronously
2) Updated to OAuth mechanism. Twitter is getting rid of their old plaintext password API in June, so this release is meant to address that. Everyone will have to authorize against their Twitter account, but in theory the OAuth mechanism is more secure.
If anyone has any problems, drop a comment here.
