Taste-o-meter

I feel so cool to be one of the last.fm beta testers. Anyway the taste-o-meter feature they have is very cool. The idea is that on every user page there is this bar that shows how compatible you are with them. For example, I am completely not compatible with BJ, I am "high" compatible (a little over half) with James, and "super" (all the way) with Anneka.
