I think the whole idea of Wikipedia is flawed. Built by copyright abusers, run by zealots... I think in this case you NEED a profit motive to encourage neutrality. Also, how much can the typical person contribute? Why trust them? Who's fact checking? Also notice how this killed all paid encyclopedias? I'm all for the free flow of knowledge, but not a fan of wikipedia. Look at DMOZ and how that fell apart. People within an organization need clear agendas and oversight.
