I've noticed that too. These comments are in the same category as people complaining about being downmodded; they don't make very interesting reading. Perhaps I should put something in the site guidelines about them.
Edit: while I'm at it, the "not hacker news" noise belongs to a more general class that I've been training myself to tune out, which is the "meta hacker news" category. A bad day here is one in which there's more discussion of the site itself than anything else. And yes, I'm fully aware that I'm doing it right now. :) But I've been resisting it successfully for weeks...
