After going to a few hackathons, I observed a trend of mostly useless, tech-bubble oriented products developed. So I had the idea of a marketplace style site where people would talk about their problems, and simultaneously provide ideas for hackathon hackers. Then hackers would visit the site for ideas, and if they build a solution, they get users immediately--the people who were subscribed to that problem. This would also hopefully channel all that hacker power into useful products. Does anyone think that&#x27;s worth building?
