Demographically, Wikipedia is white male nerds. You might have seen some stuff in the media lately about how it's felt that this limits the scope of the encyclopedia. But it's not so much that there's an anti-nerd sentiment, it's that we have to broaden the base.

It can be a bit crazy sometimes. You think you have problems with your page -- I heard that the #1 actor in India had his page deleted because some kid from a Western country thought he was non-notable. Wikipedia can be a great place to learn about science and technology, but let's say, the history of feminism? There are articles on every micro-neighborhood of San Francisco, but sometimes hardly anything on major cities of Africa.
