For those of us who haven’t re-read the rules in the last couple weeks:

> Please don't complain about website formatting, back-button breakage, and similar annoyances. They're too common to be interesting. Exception: when the author is present. Then friendly feedback might be helpful.

That's the first time I've seen that guideline. It seems like the "too common to be interesting" principle would apply to an enormous amount of comments here.
