I'd argue that a well built site with a bunch of quality content pages has the potential to outrank Wikipedia IF that site is exclusively about the subject of the query. That is to say, stay focused like a lasor beam if you want a shot at ranking well at Google.
unfortunately this is getting harder and harder to do Reno. I've been trying for about 6 months now just for fun. I targeted a niche, 3 word keyword which wikipedia ranks #1 for. bought the exact match, aged domain (registered since 1997, .com). wrote thousands of pages (over 6 months) of unique content, 6 months of link building creating 5 times the page links than WP has for their page and 4 times the specific keyword anchor text than WP has pointing at their page. WP's entire page on the subject is 270 words. We have a 1000+ page, exact match domain, laser beeeeeeam content website dedicated to the subject and nothing but the subject, no adsense or any other advertising or outbound links and we have not yet been able to shake WP out of the tree.
now from a business standpoint I'm not that worried about it, WP sucks so bad on this topic that we are not losing much traffic by being in the second spot. I guess it's just personal!
