Cleaning Out My Friends List

I've been making an effort to spend more of my gaming time playing multiplayer via Xbox Live as of late. There are many reasons I don't put many hours into online play - the most prominent being the fact that I can't stand being yelled at by 12 year-olds who shouldn't be playing mature rated games anyway. Come to think of it, the random banter you hear come out of the younger players mouths is more annoying than the whining, but that's beside the point. Playing with the "general public" usually isn't all that fun and is often spoiled by 1 or 2 asshats.
