Wikipedia founder Jimmy Wales wants to create an open, editable search engine. In other words, spammers and advertisers can more easily mess with the results? As much as I love the idea of "crowd wisdom," I don't have a lot of faith in people behaving themselves. People game Digg.com all the time despite their best efforts to prevent it. Imagine the possibilities with a full Web search engine. The constant battling with people out for their own best interests will likely render the results useless.
