When I grew up, going out meant going to the Disco. I was never good at it. I felt that disco took away the things I was good at. Intelligent talk was my main weapon in the struggle for girl attention (and that is not a very strong one to begin with), which doesn't work so well if you have to shout all your utterances at the top of your lungs. 'AND NIETZSCHE SAYS.' Beer drinking is something else I'm good at and that isn't much fun either at the price/my income ratio back then in these kind of clubs. And then there was disco dancing which I never really got. Now, if you got touch the girl, I could see the point, but moving around for fun?
Later it turned out that drinking in a pub was also a form of going out and the whole dancing/loud music/not talking thing was avoidable. Much later lounging seemed to be a cool thing too and all was well. And now blogging, which is close to my natural way of expression. Okay, it is not going out per se, but still.
Probably if you wait long enough anything can become popular.
