What I found annoying though was finding out I'd typed say a 141 char message, I get a notification through growl but the text is gone, so I added a couple of lines to copy the text to the clipboard in the event of an error, that way I can try again, cmd-v in the last text and modify.
And for fun I've got it to check whether Adium is running and if so change the status message to the Tweet, I may drop this though as it got me in trouble recently as I had forgot I had done it and sent a Tweet about something I was doing and a contact in Adium sent me an IM asking about it, too much info too many places perhaps.
