Mastodon (software) Updated +Created
Of course those racist Nazis are a bunch of idiots, but how can you be surprised when freedom-of-speech focused tech gets used by them? www.theverge.com/2019/7/12/20691957/mastodon-decentralized-social-network-gab-migration-fediverse-app-blocking
Obviously, a few large instances dominate the user base for all practical purposes: kevq.uk/centralisation-and-mastodon/. And likely the network splits into hate-speech/non-hate-speech blacklist boundaries. And since the dominating closed networks will never lose user counts (???), the only instance that dominates will be the main hate speech one.
The flagship instance was mastodon.social and then in 2020 they closed signups for it and created a secondary mastodon.online.
The multi-instance thing is confusing and problematic. E.g. replies and likes might not show up across instances in some occasions: www.reddit.com/r/Mastodon/comments/ynt7ta/is_there_a_way_to_see_post_replies_displayed_on/
The "advanced interface" feature is bad. Really bad. MacOS file browser inspired.
