I find it all fun, perhaps that's why I'm sticking my neck out here. I find it mostly 'show & tell' for adults.
The threads I like myself are ones like 'DDW' posted regarding the Bahamas or Jon posting about his experiences leaving New Jersey with snow on his deck. When the discussion turns to 'mine is better than yours because' it leaves the poster open to some jerk like me grabbing and running with it. Not much different from political discussions after a few cocktails. That can be a lot of fun till fists start flying.
