@TedUnderwood @Gargron bluesky you looked at there, is developed by twitter. But it's a bit pointless to do that, as there is already an protocol called ActivityPub that is managed by the w3 which also standardised HTML and the whole Web. ActivityPub is used my Mastodon and a lot of other applications. If you don't like Mastodon, you can try pleroma or misskey and still are in the same network of networks, still have the same contacts.
