Isn't there an old saw about every big "Web 2.0" business being something that took what people were already doing but made it "social"? So Facebook made blogging social, Twitter made texting social, etc.

10+ years ago I knew a bunch of people who had personal blogs, but of course most of them were filled with "sorry for the lack of posts recently" type posts.

I'm not on Facebook, but I understand why it's popular. The more people who might be reading, the more reason there is to post stuff. So it makes sense that everyone winds up in the same network.
