100%, and thats not a comedy pick. All of it, good and bad, serves as a huge psychological pressure valve and a good place to get out ideas/thoughts/frustrations with a diverse but generally polite but interesting group of people. And that extends to all of the AT forums, not just ATOT.
The closest equivalent I can think of is stopping by the bar on the way home (i don't but I think this serves the same purpose). You have a group of people that you "know" well enough to have a comunity but are also anonymous enough that there is less pretext and social pandering, which is the real social lubricant lies in any scenario.
