Someone once told me that the reason they don't read Less Wrong is that the articles and the comments don't match...I have no idea what that person is talking about. Do you?

Yes.

Back in Overcoming Bias days, I constantly had the impression that the posts were of much higher quality than the comments. The way it typically worked, or so it seemed to me, was that Hanson or Yudkowsky (or occasionally another author) would write a beautifully clear post making a really nice point, and then the comments would be full of snarky, clacky, confused objections that a minute of thought really ought to have dispelled. There were obviously some wonderful exceptions to this, of course, but, by and large, that's how I remember feeling.

Curiously, though, I don't have this feeling with Less Wrong to anything like the same extent. I don't know whether this is because of the karma system, or just the fact that this feels more like a community environment (as opposed to the "Robin and Eliezer Show", as someone once dubbed OB), or what, but I think it has to be counted as a success story.
