A lot of the classic arguments have played themselves out (i.e. every spin-off hosting related forum now has a unique definition of "unlimited"...probably due entirely to WHT debates) or the arguments are no longer relevant (i.e. power concerns in filling a rack.) Most discussion is over before it starts.
The more low-brow stuff (i.e. "ermahgerd colocrossing!!!1") has found it's way to alternative forums that have different moderation standards.
If what I hear is correct, WHT actually asks for proof of ID when you sign up now. If true, I don't think they're doing themselves any favors, as I certainly wouldn't sign up for a random forum online if that was required. If they do I understand why, just saying I'd simply not join if a forum ever asked me. I don't want to test it, lest I risk the ban hammer.
