oxala75@drcaberry I think Black Mastodon is just black people across all Mastodon servers/instances/neighborhoods. I think the Black Fediverse is black spaces across all of the potential fediverse (e.g., Pleroma, PeerTube, Misskey, Pixelfed).
@drcaberry that said, I'm not familiar with any part of the fediverse beyond Mastodon (and barely that).
