I haven't really got anything to add to your comment, so just a quick note to nod my agreement.

I'm not one of those people who friend everyone back automatically (Donna, I believe you do that?)

Mostly, yes. Unless they're obviously trolls or weirdos. It's because I'm curious as to who friended me and having them on my flist is the easiest way to find out. I'm not so much focused on a certain kind of LJ, either; I read RL stuff as well as fics and essays.
