What if... you had one Fedi account on a generic headless #ActivityPub server that simply hosts and federates your data... and had C2S UIs for microblogging, long form writing, media editing and sharing, link aggregation, games, fitness tracking, and so on, that all used that same Fedi account. Technically, it's a similar concept as ATProto (but no relay and app view) and Solid Pods (but no RDF).

It seems possible... if we can improve the AP C2S API/protocol sufficiently.

@steve I've built the server part already, that was 5 years ago. Still waiting for people with the skills to build the UIs though...

@mariusor @steve Does your server work with https://checkin.swf.pub/ ? Or https://github.com/evanp/ap ?

@evan I could login, it did some stuff but then it redirected me to the login page again.

Hey @evan ... I've looked into why I get issues with checkin.swf.pub, and it could be that I'm doing something wrong, but it hits my servers using client_id=https://checkin.swf.pub/client.jsonld

Which, when gets dereferenced serves an ActivityPub Actor(ish) like document instead of the Client ID Metadata I'm expecting.

I remember I was arguing with Emelia about how to server both formats from the same URL, but in the end I decided it's not worth my time trying to do both, and I'm just expecting the data model described in the RFC7591 Sect2: https://datatracker.ietf.org/doc/html/rfc7591#section-2

@mariusor I'll check it!
