Problem is that one can't measure social skills against anything other than ones own standards, and those evolve as generations go. In the eyes of a 1900 upper middle class person, we'd probably all be degenerates.

I'm born '86, regular access to technology since the early nineties. I'm a social kind of person, have many friends. Sometimes I just want to lock myself in for an entire weekend and play video games for 16 hours a day. Other times, I'll be having barbecues or going dancing.

And as many here have already stated, the extremes go smoothed over by time.
