For all of you people out there who want a wiki (and what self-respecting online person doesn't?) I can't speak highly enough of PBwiki.com. It's easy to use and best of all it's free. It's hard to go wrong with free right? I've been using it to keep all those damned commands I always forget and end up googling. And before you post any swmarmy comments, I know those commands are lame and that I should remember them.
Full disclaimer: by posting this I get my space on pbwiki doubled. But I really do like PBwiki. I've been meaning to write about it for while now.
