We all know that the convo that happens here is discrete from what happens on the actual source. In lieu of the i/o plumbing that Disqus, et al, are forging, isn't there some kind of social contract that commentators should be a party to?
As Fred said, "[The author's] reward is the comments it generates. That's how bloggers get paid."
I think this is especially true if there's serious criticism. I'm not sure how I feel about someone posting a comment that flies here, but would be regarded as a flame in context (as happened on my submission http://news.ycombinator.com/item?id=203609 )
(Ironically, I was downmodded after responding flippantly to the in-context flame)
Any thoughts?
