Gaming discussion being the most popular, obviously being the only place to chat about games not to much more then a month ago.
Sony discussion interestingly more popular then Nintendo discussion, by about 2,000 posts.
However Nintendo seems to have more to talk about, having more threads then Sony.
Microsoft lagging behind dramatically for those interested.
Off topic out-weighing all the games boards, but still a far-cry from IGN's whopping 41,000,000 posts in just ONE of it's OT boards (Vestibule).
Other site total posts:
The Magic Box: 395,132
1up: 351,250

Screwattack: 59,611

And the worlds largest forum is gaia.com: 1,109,599,000 (over 1.1 billion posts!!) <<< This one really isn't fair seeing as it is kind of like an online game, every post ears you in-game money, therefore this describes the reason it has so many damn posts.
