> I'm sure most of my friends have no idea I'm seeing this, and if they did they would probably interact with FB even less. I'm very hesitant to interact with FB at all now, and just do a quick scroll through every other day.

That's exactly how I feel. Facebook shows to me, to the right side of the screen, a feed of all the comments and likes my friends make everywhere on the site, even on pages I don't like or on walls of people who are not my friends. It's like some kind of "spy mode" which makes me reluctant to comment anywhere (what if my friends will read it?).
