I work with some guys who either have a problem with profanity or they have some kind of weird fettish for it. Either way, they have put up a site called Twittertale to track all sorts of vulgar tweets on Twitter.
<p>It is written in Rails, and has a nice and clean interface. Something about just feels dirty, but I can’t stop going back and checking for new dirty posts. So everyone twittering out there be careful, because someone is searching your tweets for those dirty little words!</p>
