Rashmi Bansal writes about the problems with user-generated content:
The idea of ‘user generated’ content is a great one. And it works when you have millions and millions of people contributing such content – like at youtube.com. From a mountain of boring / mediocre trash you find a few gems and the system is designed such that users push these gems up to the top of the pile.
But when the number of users you attract is fairly low… you don’t have enough gems. And the trash attracts more trash and repels people who actually have quality content. Because you haven’t created an environment where the ego-driven creative types would like to showcase their work.
