FirstFollower is a simple site that pulls up what should be your first follower that you ever gained. Now Twitter has made some changes to how followers are listed, so I am guessing this is accurate. Either way it is a fun site that works against any name. A great two second time waster for sure.
You can also take the randomly generated tweet it makes about the follower it discovers and send that if you wish. There is both an English and Russian version of the site.
