Very interesting points. Kind of a tangent, I had kind of felt nostalgic about the days of the personal/hobby websites you appear to allude to that seemed so prolific before Facebook/etc, and wondered why things had changed so much.

It makes sense to me that now someone who used to be motivated to build a site about their life or a topic of interest now may often just sign up for a service like FB and occasionally do a post with an article, picture, etc about themselves/their interests. It seems to require much less effort for folks, which is perhaps why they do this. I lament the change somewhat and wonder what the future holds for this type of thing.
