@paul This is an important question to keep iterating on as the #W3C moves into its new era of having a board of directors, and the #W3CAB starts focusing more on their Vision work (https://github.com/w3c/AB-public/tree/main/Vision). Us browser folks have been biased toward "practical" #WebStandards that get implemented in browsers, but #ActivityPub is proof that the more aspirational server<->server ones can be important too.
