Which other Twitters want to be my friend?

A thank you to Wilfred for being my friend ;-)
But seriously, I thought I would try the Twitter badge which shows my friends on Twitter. It really does work and certainly is a lot more interesting than just my own mucking about. The one thing I did notice was that it was a pain to find out just who is on Twitter. Of course I can start inviting everybody, but I just want to find those already on twitter...
