Not sure about that. If you consider any good collaborative model (based on mutual benefits) you will prefer fans and geeks rather the regular not-caring folks... If Jimbo succeed when trying to put together the fans of several different kind of subjects, he should be able to build a really neat search engine.... Remember, there are people obsessed about a lot of things beyond Star Trek and etc... And on collaborative model, this weird people are exactly the ones you can rely to freely and happily help you building some great stuff...
