I've actually tried to do all of that!!! No, really, I have. The problem is that I don't know what half of the terms are in the settings. I don't know what the difference is between the wall, a home page, and what the heck's a news feed? Then there's the fact that I don't know how to differentiate between what comes to my page and what goes out. (Insert confused smiley here.)
And what's with the fact that sometimes when I go in, posts from days or weeks ago are on the top of my list (wall?)? You're right, I don't get it, but I also don't care to invest the time in it right now. So I just

at some of the pictures that come through,

at my friend that can't stay out of some cafe, and

at happy news that I find.
I know I need a teen, but my dd12 is just not interested in it. Thankfully!
