JT set up a Mob Rater instance for YAPC::NA at ideas.yapcna.org. You can suggest ideas for YAPC and vote on what other people have suggested. This isn't a commitment to act on any of the ideas, but it's a great way for organizers to see what people want and how many people like the idea.

This doesn't have to be suggestions for new things, either. Don't like something? Maybe everyone else does too. Tell Mob Rater you want to get rid of it. See what other people think.

This is even simpler than voting for lolcats. You get a Yes, No, or Skip without having to see a single kitten or forward anything to your friends.
