To be honest one of the reasons I like that thread is because - particularly talking about speculation on new tech - it's a good way to test out whether the theories withstand the test of hostile questions and comments. Talking about it in a thread of like minded people is just a round of "yes' - not really a place to resolve how things might work out.
That's why a lot of guys fall out of that thread. In fact if you go look at the OT Justice/Ban review thread there was quite a few of those guy whining about the thread saying they get "hounded" out for posting anything positive about xbox.
To me though, it's just that the arguments have to stand up in the face of cross-examination - if they don't, give in or get banned.
Also, a thread like that wouldn't (and doesn't) exist on Reeee. Personally I just lurk on Reee - it has better "insider" stuff but I steer clear of the political correctness bits. So in a sense the existence of the Speculation thread here is what differentiates GAF. For better or worse....
