Today I found out about Friendica. It's basically a decentralised version of Facebook, in the same universe as Mastodon and Pixelfed.

It also allows you to link to Twitter and read and tweet from the Friendica interface, so you're not tied to Musk's algorithm and adverts.

Being decentralised, it's also self-hostable, so I might give that a tinker. I had a play on on one of the public servers and found it doesn't seem to be a "live" feed (it was behind by about 3 hours for me) and you can "follow" both people on Twitter and on other Fediverse platforms.

I personally haven't tried that yet, but in theory, you should be able to follow people on Twitter, Mastodon, and Pixelfed and have them all show up in your timeline.
