Comments should matter more than votes. A thread with all votes but no comments is a meaningless number, but a thread with all comments but no votes is exactly the same as that thread with votes.
That particular weighting doesn't make sense to me. Clearly some people vote by commenting. Which is as it should be.

I disagree. If you like something, vote for it. If you don't like something, comment on why and don't vote for it. If something just doesn't belong here, flag.
