Why don't they go back to the old design? Also make it easier to find people and get rid of the spam. Just make it more simple. Also the mashup with facebook is a stupid idea.
I don't have a facebook account but idk about this. Will users get another username for their email address or use their vanity usernames? The under 18 crowd will use it because like another poster brought up, my brother also doesn't have a email address. He tried using mine.
