The claim to fame of Yahoo! was, we hire people to look -- originally, not anymore -- we hire people to look at websites and tell you -- if they're in the index, they're good. This, on the other hand, is what 60,000 passionate volunteers produce in the Open Directory Project, each one willing to spend an hour or two on something they really care about, to say, this is good. So, this is the Open Directory Project, with 60,000 volunteers, each one spending a little bit of time, as opposed to a few hundred fully paid employees. No one owns it, no one owns the output, it's free for anyone to use and it's the output of people acting out of social and psychological motivations to do something interesting.
