Or the 'whats the difference between hacker and crack plllzzzzz'
"The difference between RAID1 and RAID0 is that the zero stands for how many files you're gonna have after a harddisk failure."
I think that a "Social Forum" would help build community. It would also allow new comers to acclimate to how people behave around here. In terms of a productive forum, this is priceless. Also, it gives people an appropriate outlet for thoughts that wouldn't necessarily fit in the other forums, but could still benefit the community.
A "personal accounts" forum would also be pretty nifty for people to share stories and learn from them. However, I imagine that would probably be a moderator's nightmare with the many "Look at all the illegal activities I partook in!" threads. Though, I would like to give user's the benefit of the doubt on that one.
