The core community is passionate about quality and getting it right. If you want to read some good criticisms of Wikipedia, probably the best place to go is to the Wikipedia article called 'criticisms of Wikipedia'... It was either the dumbest thing or the smartest thing I ever did. The dumbest thing for the obvious reasons, but the smartest thing because I don't think it could have had nearly as much impact as it has. One of the key things that inspired people to put a lot into it (was the charity aspect).
