I noticed the s.gif change (so I could update my extension) but the arrow is still showing as the link he has.
I am sure it will get fixed soon enough.
I'm guessing, just guessing, that HN being down was to install the security cert. Maybe had to do with that, and some minor assets still being served of of http as opposed to https which is why we are getting the errors and css problems. Should be an easy fix hopefully. Good luck HN.
I never thought the site was pretty but I was shocked that it could get a whole lot worse. It must have been pretty jarring if I was able to spot the immediate difference.
Really I don't mind that it isn't pretty as it serves it's purpose well and I like the feel of it as it is (with css).
