Despite the flippant title, this seems like a very good idea.<p>I believe that positive feedback of this kind is the sort of thing that allows wonderful sites such as stackoverflow to exist.<p>The competition itself seems accessory, though. The real interesting bit is that Wikipedia is essentially adding its own "like" or "+1" button. I hope it keeps the term "love" button, even if it does seem out of place (at first!) for stuffy old Wikipedia.<p>Now that I think about it, maybe this will begin a push to have Wikipedia seen as less of a stuffy old place filled with angry pedants and more of a "community garden" of knowledge. Not that I'm advocating less editorial integrity, its just that Wikipedia really needs more measures to lessen the perceived hostility (once you get inside the place), so this seems like a little start towards that end and a big plus to me.
