I read a story on HN a while back about a guy who used an algorithm to generate his passwords. Don't have the link but something like combining easy to remember bits of personal information. e.g mother's name, kids birthday, maybe changing the case of these. Also adding something site specific like the last three letters of the url backwards. It's easy to remember passwords this way but if one gets out they're all vulnerable if someone looks closely.
Yeah, it would be nice if they had an open server that allowed you to sign up and check it out. There's nothing stopping anybody from setting one up though.
