I'm a bit late on the gun on this one, but I just read through what you and insomniasexx were discussing and I think what you said about the dispersing sex is really interesting.

My experience actually contradicts this--I've personally seen that male-male bonds have been stronger than female-female bonds. For example, my group of male friends and I fight all the time and give each other shit constantly, but in the end it's all good, no matter how heated it gets. We get over it in a matter of hours. However I've seen my sisters and my mother lose female friends over the most trivial of matters, petty arguments. This is a generalization of course and what seems trivial to me (a male) may be a much bigger deal to a woman. I don't know.

Re-reading what I just wrote I'm now realizing that it makes me either sound like I think women are petty creatures or that my sisters and mom are bitches. Neither is the case, but this is just my personal experience. I think part of it is that I was an athlete and grew up in the 'locker room' culture and the idea of 'team brotherhood' surrounded me. So it's possible that my view of male-male bonds being stronger has been influenced by that, whereas (and again, another generalization) most of the males on discussion-based sites like reddit may not have had that and thus feel as if forums are the best avenue to have those discussions.

I come from a house that was practically damp in estrogen and my little sisters are big into Instagram and Pintrest and Facebook, basically all of the social network sites you would normally consider to be targeted towards females. They're your proto-typical girly girls. As you mentioned Pintrest and Facebook aren't really discussion-based sites but then insomniasexx brought up how girls can talk for hours about something like a 10 minute hookup whereas for guys the conversation lasts 10 seconds. But then online, guys are riffing for pages on a myriad of subjects where the majority of girls are content on sites that don't really feature any heavy discussion. I find that strange.
