It's actually still 12/28/19, but I'm setting up the yr/mo/day folder structure I think I'm stuck with, if I want the new blog to sit side-by-side with the old one. It doesn't actually matter too much, I don't think. (The posts will all still appear, whether they're in hundreds of nested folders, or all in one giant pile. But the URL format matches, this way, which I think will be helpful in the next couple of days. Or maybe not!)
UPDATE: Okay, it's 1-1-2020. Let's push this repo and see what breaks.
Particular apologies if I break-slash-spam your RSS reader. Really not sure what it's going to do when I cut over an entirely new backend.
