Mog

Another music-oriented social networking site: Mog.com .
It sounds almost exactly like last.fm, but perhaps since this is more "social networking" oriented it will make the information gleaned about your listening habits and musical taste a little more useful. E.g. it would be cool to see a list of people in your physical neighborhood who like the same music that you do. Last.fm doesn't really let you coordinate your musical profile in that way.

This is a screenshot of the Mog-o-Matic software that they use to somehow determine your worth. I don't know what it's doing really, only that it seems like it is somehow making a catalog of all the music on my hard drive. Kind of scary actually... last.fm doesn't do that, they just passively index the music you listen to as you hear it.
