So, I made some changes to #tagspub today, concentrating on interoperability with #misskey. I had a lot of fun setting up a Docker environment with a Misskey and a tags.pub and watching them chat across their imaginary network.
If you're a Misskey user, could you try following a tags.pub account like @misskey ? If you've tried before, and it's been stuck, make sure to cancel the follow and try again. Let me know how it goes!
