I'm a member of several mainstream boards and they are VERY user friendly. Most are money, food and medical (personal and biz) boards though.
It's funny at some of the things the investment boards won't let get posted (one became so heavily moderated I stopped even reading it) then I come here and see all kinds of wild stuff
Though as far as personal information, this board is much more moderated. One of the investment boards has guys with access to Pacer and other dbs and damn if they can't dig up every piece of dirt possible and post it. Except for spam, it's a mostly self moderated board.
