Are you kidding? I'm an X'er and my parents are boomers, and I can assure you we all had an absolute ball before Facebook came along. "Not going out in the evenings to see friends, sitting watching TV, having narrow social lives" - seriously? Maybe in your family / community / culture, but not mine, and not many, many others too.
I'd even be tempted to speculate that those of us who aren't Facebook addicts are the ones who are able to socialise just fine without it, thank you very much, if it weren't for the fact that I know plenty of good-living, fun-loving Facebookers too.
