So in case you haven’t heard, registration for the 2009 event opens next week. That means that it’s time to start talking ideas and finding teammates.

Don’t have an idea yet? How about this one: you could build a web app to organize Rumble web app ideas and help people find teammates!

Oh wait, someone already did that.

Say hello to rumblestiltskin, a small Rumble idea organizer created by Dan Croak of Thoughtbot. At the site, you can browse a list of ideas, submit your own, and find potential teammates, too. Check it out; there are already some pretty quality microapp ideas listed there.
