I find this to be a strange comment. Quadratic voting is much better if we have to reach a consensus and want to protect minorities. So it has it's application (and is woefully under-used). But surely it's not always the best method. I think often you want the most popular comment to be at the top of the list, because it's what appeals to the most people. Secondly, one of the big problems that quadratic voting addresses is when an ambivalent majority outweighs a minority simply because everyone votes. But not everyone has to vote on every comment on a site like reddit, so the ambivalent majority is already ignored.
