@smooth is one of the whales I respect most. Always finding good content and making meaningful comments.

I do feel that positive comments get more upvotes, but that may simply be due to the fact that there are more positive comments than critical opposing comments.

With the reputation system in place I think people are being more careful not to offend do to the fact that you can flag content without giving reasons why you flagged it.

I think there would be more constructive criticism and respectful disagreements in the comments if people don't fear being flagged for their opinion.

I have proposed a flagging system with feedback that would force users to say why they have flagged content. New Flagging System With Feedback

I'd love to have some of the whales and dolphins comment, regradless of whether or not they wish to upvote it. I think the feature will add so much long-term value, that short term upvotes and dollars while appreciated and helpful will pale in comparison to the what is in store down the road.
