There are lots of Fun Data Problems. Elsevier's having a competition to propose solutions for some of them, and there's a chance to vote on which challenges people tackle! (The rest of this message was posted by William Gunn from Mendeley on the Open Science Framework mailing list) Elsevier are doing a Grand Challenges in Research Data competition. Here's how they describe it: "The goal is to pick one or more open problems and, then, invite research and industry teams out of there to compete and provide solutions that improve a given baseline. Those kind of competitions are common in the industry (e.g. Netflix <http://www.netflixprize.com/>) and are not new to Elsevier <http://www.elseviergrandchallenge.com/> either."
