Like with books, music, and other "necessities," I just keep them. I think I'm incapable of dropping anyone. I can move people up and down. Also, if I warm up to someone I didn't really like before and then they do something to remind me why I didn't like them, I'll take them back off the list. But if you start out as a favorite, you're pretty much stuck. And that is why I ran out of space in my profile.
