Not so. Reddit's system works that if a post get 1000 upvotes and 500 downvotes (66% liked), it will be scored worse than a post than gets 10 upvotes and 0 downvotes. Basically what it does is penalize controversy, which is the perfect decision for a website that is about mining the most humorous and widely-liked response. Anything that is 51% liked and 49% disliked (e.g. political individuals mentioned in a non-political thread) gets bombed to the bottom almost immediately, which is exactly what most redditors want. The other brilliant thing it does it let the user adjust this prioritization if they so desire.
