Anyone saying a link from Wikipedia, or even better an article (even if its a stub).....well I don't think they're someone to follow on this forum. Wikipedia is one of the most visited sites on the net and even if it is no-follow to think that links from the site carry no value is frankly crazy. Aside from instantly being indexed and carrying all the markers of a site Google would love (human written and better yet peer edited) it also carries an outstanding PR.
