Absolutely believe in chronotypes. Retired now, thank god. But my best REM sleep has always happened somewhere between 5 am and 9 am. Even when I had to follow everyone else’s schedule, I absolutely had to be able to sleep in Saturday morning. If I didn’t, at some point I’d have to go off in a corner later in the week and just sort of waking-dream to catch up on REM.
Oh, eww. A Meta/Twitter mashup? No. Just no.
I loathe Facebook, although my church uses it, so I’ll grudgingly check it once in a blue moon. Never quite got the whole Twitter concept. Used Twitter intensively only once or twice for simulcast commentary back when the Sharknado series was a thing. And found I could sometimes get faster customer service on (for instance) airline snafus, when company portals were unresponsive, and phone queues required waiting through 3 hours of drecklich Muzak.
“If Meta wants…” My concern is that the only conceivable motivation Meta could have for investing money in such a project is making more money. If, in the process, Meta destroys the eco-structure of the Fediverse, so much the better—less competition, more money for them.
