I guess in short; the social dynamic is to me much larger than it appears on the surface. And though it could be considered a 'waste of time', what other activities in life could not be labeled the same, depending on one's persective?
Right. I used to post on a pregnancy board nonstop, where we spoke about everything under the sun. Same goes for other 'common interest' internet sites.
It's a waste of time if you consider interaction with certain people to be just that. Does it really matter that there is a common background we share that is a former/current religion? Or do the people here come first now?
