@alcinnz @datatitian I would *love* for Facebook and Twitter to adopt ActivityPub, but it seems they really *want* to have walled gardens, so it's hard for me to be optimistic there.
I think Google or Microsoft (!!) would be more likely to participate in ActivityPub stuff at this point, because they're more nervous about not having really a big inroads in the social networking scene these days afaict, and maybe AP could help them
