I would like to raise one point that's tangentially related: why is it not easier to find a page explaining the community guidelines ? AFAIK you have to look them up yourself.
The navbar has links to new, threads, past, comments, ask, show, jobs and submit, but none of them even give a clear redirect link to get to the guidelines ... wouldn't it make sense to add them to nav, or configure the site such that they're displayed the first time you visit ? Always seemed a bit funny to me from a design perspective.
(They're also not in the footer of the comment page and a link in the otherwise empty header could be useful for new users.)
