Something like IndieAuth, yep! I was thinking about how Bluesky uses domain names as usernames, and how a ton of people are scrambling to direct people to (and in many cases build) websites. Also issues with the fediverse (the last instance I was on poofed out of existence while I wasn't looking), and microinstances (ie GoToSocial), and walled gardens, and, and, and ...
And also, honestly, about people objecting to using domain names for identity because it Costs Money, and Cohost going under because even 15-20% of MAUs subscribing Isn't Enough, and the expectations people of social media, and how most of the Fediverse runs on unpaid labor.
Consent&Magic is something I absolutely want to finish writing, someday, it's just a complex topic and I want to get it right, y'know? So. No promises.
