Housekeeping note:
So yeah, I attempted to migrate to mas.to early on and almost immediately tried to roll it back. Turns out you can KIND OF do that, but 1) your followers don't roll back with you automatically, and 2) there's a 30 day cool-down period before they let you try again.
That period is over, and this time I'm going over for keeps. My contribution to load balancing. If things go to plan, you won't see a difference, so back in a bit...
