I felt the confusion you are talking about. If readers could be expected to read the top-voted replies (RTFC), then the current distribution of votes would be ideal: The interesting article gets some well-deserved attention, and the skeptical replies give a counterbalance. But if readers don't read the comments, then frankly I think this article got too many upvotes when compared to many others.

Offtopic: Is there a meta thread somewhere discussing the semantics of votes? I am happy that we don't use slashdot's baroque insightful/interesting/funny distinctions, but some consensus about the meaning of +1 would be nice.
