@rigo @CommissarMatis And much of ActivityPub didn’t start at the W3C. It was an iteration of OStatus. And prior to that, work done by @evan with his startup identi.ca.
Now one thing I will say is that W3C validation was important, and was probably what created momentum for broad adoption.
Anyway, competition isn’t bad. If anything, AT protocol could be the kick in the pants to improve ActivityPub.
@atomicpoet @CommissarMatis @evan I don't think a single thing was started at W3C, except PICS perhaps. And I'm all ears when it comes to improving ActivityPub.
