You know your protocol is completely dead in the water when the maintainer of the only Android client and a member of the committee overseeing the protocol does not care about implementing any extension made in the last decade. Truly says a lot about the protocol.

@silverpill XMPP, but it also applies to ActivityPub. They both have very similar issues. Nobody learned from XMPP and OStatus, so it's basically the same but with JSON instead.

How many ActivityPub editors/writers actually implemented a server using their own spec they wrote?
