The option to rate a comment as "good" or not has disappeared, I guess it was deemed useless as people only rated a comment good if they agreed with it?

I wish there was an option to rate whether a comment made a substantive contribution to the debate, i.e. made a rational argument, rather than just vented or stated an unsupported opinion or a joke.

A comment can be civil, so I feel I have to rate it as such, and yet make no substantive point. I wish those could be dismissed, they just add to the din.
