I really dislike that mechanism. I want to read controversial posts because they might challenge me. I have to resort to using /active to get an uncensored view (at least that seems to be what /active does). Also, getting many comments on a submission doesn't necessarily mean the subject is controversial -- it could simply mean that many people have experiences to share on a certain subject.
Can we just let the up votes do what they're supposed to do and stop trying to distort the system with weird arbitrary rules?
