This works for technical topics, but quickly falls apart in certain topics of conversation. When a user-base skews one way politically, this is a terrible feature. People are blind to the fact they're chiseling their own echo chamber. Edit: how is downvoting political opinions (and therefore reducing the post's visibility) beneficial to anyone? It's a shallow way to make the down-voter feel good temporarily, and dissuades actual discussion of other philosophies. At the very least, political downvotes should require a response.
