Okay, all you techie people of Mastodon whose posts I rarely understand, help an English major out:
I know that I can download all my #Facebook data.
But is there any way to set up an imitation of "Memories" privately with all that data, so that I can see what I've posted on a given day over the past [redacted] years?
If anyone wants to make a Fedithing that will do this, I'd happily subscribe. #Meta
