Shamus Young (of DMotR fame) is understandably irked at the nitpickery that has come with having a big readership.
I confess uneasily to being one of those commenters, sometimes, although I like to think that I’m able to restrict my nitpicking to areas where it really is material to the point or argument being made. (Example of useful nitpickery: if the actual author of the linked post was Frank Johnson, correcting my error would be material; non-useful nitpickery would be pointing out that nitpickery isn’t a word.)
From a commenting perspective, probably the only thing Shamus can do to move the situation in a direction he likes is to create a circle of regular, non-irritating-jerk commenters, and ask them to use peer pressure to keep the jerkish behavior down. Ironically, I’d like to make this helpful suggestion at his site, but he’s closed comments because he’s sick of the jerks. Hopefully he’ll see the trackback. ;)
