I would say you are a content farm, mainly because I think you'll use Wikipedia content to drive traffic to your pages even if there is no user generated content on them. There are two things you can do to reduce the spammyness of this concept: show Wikipedia's content in an iframe and show only pages where your users have actually commented. That said, I'm still waiting for someone to actually fork Wikipedia. I think it's about time.
