>It's not an all-or-nothing. It's an extra piece of information...But when it comes to trying to assess the quality of the comment, more data is better than less.

It could be an extra piece of disinformation, which can make it more difficult to evaluate.

I suppose I'd like it if there was no way to sort. What happens on Reddit is that such comments easily bubble to the top, and they're often wrong, or just making a silly joke rather than being informative.
