I assume a fair number of those pages are automatic updates, but a fair number of people also seemed to have anticipated 2021 by a few days. Ever since Brian Dean told everyone to do it, that little tip has become a lot less useful.

This is a fundamental problem. Maintenance tasks of all sorts - Y2K bugs in code, deteriorating bridges, etc - get no glory. Politicians can't get photo ops at a properly maintained bridge.
Anyway, Happy New Year everyone!
All in all, 2020 turned out much better for us than I expected back at the end of March. If 2021 merely comes in as an "average" year, I'll be quite pleased. My standards have reset a bit ;-)
