I guess I'll be the boring one and say I don't really like a cluttered postbit. The avatar is the most important part there. If you have stuff below that's twice the size of the avatar, the avatar loses its focus. An extra line or two won't make too much of a difference. But some people have a lot of favorites, and that takes up multiple lines on its own. And personally, I don't find favorite Pokemon or a type to be important enough to warrant a place in the postbit. We already have an About Me on our profiles for all the various specifics.

But again, I prefer a tidy postbit.
