@evan @jalcine Thanks for sharing your rationale for using "ActivityPub API". Given "client to server" is used 22 times in the spec and "ActivityPub API" (which could also apply to the server to server REST API) is not mentioned at all ("Social API" is mentioned once), it could be considered more insider jargon than "client to server" (C2S). I've tried using the various terms in discussions and "C2S" or "client to server" tends to lead to less confusion. I suppose it's one of those YMMV topics.
