Many people (including Steven Fry) moved to Mastodon. As someone once commented:
"The problem isn't that Elon Musk owns Twitter - it's that we don't."
I wasn't aware that you can create accounts for your friends - thanks for pointing this out.
I hope your back recovers soon.
Some of those who went to Mastodon did not actually use it for long. Online social networks have become fragmented. There's no one platform that everyone goes to. This is why we need open standards to link them together.
I agree. I haven't used it much since joining.
