The #Whiteness of #Mastodon discusses the problematic nature of the #Fediverse for minority groups, including #black, #disabled and #queer / #lgbt. Interesting comparison to #twitter in terms of moderation of racist (et al.) posts, building community, and expressing identity. Also a good critique of the difficulty to change the federation and the problematic nature of "make your own #instance" as a response. Worth listening to or reading.
