Google's "Other Contacts"

I use Google contacts now, since Yahoo upchucked on me. Still no gmail, because I've been wracking my brain for three weeks trying to think of the perfect username. Please send suggestions. Thx.

Google has this weirdness with two groups of people- your actual contacts, which they call "My Contacts," and a mysterious group called "Other Contacts." Other Contacts seems to include friends of friends, although I have absolutely no idea where they are pulling them from. A bunch of Lauren's friends appear there. Several siblings of my friends, some of whom I don't know at all, other than their names. My friends' children. I don't know. You're really freaking me out here, Google.

If they are friends of friends, or contacts of my contacts...

um... which one of you has been holding out on me that you know Jon Bon Jovi?
