People had the same thought in 1995. "Consider today's online world. The Usenet, a worldwide bulletin board, allows anyone to post messages across the nation. Your word gets out, leapfrogging editors and publishers. Every voice can be heard cheaply and instantly. The result? Every voice is heard.

Current systems for ensuring the right content filters to the top are breaking. It's a rich area for new innovations.
