I deleted my Facebook sometime ago when I noticed an acute "icky" feeling every time I used it. Whether it was the posts complaining about whatever the latest outrage was (Supreme Court legalizing same sex marriage, etc) or the barrage of games, or whatever else, the signal to noise ratio was awful.

That was about a year ago. I don't miss it, and I don't feel that I'm missing anything. I think there are plenty of niche, high value aggregators of content, and ways to "connect" that are more useful to me. Such as where I am posting now. And I don't have to feel bad about myself when I use them.
