https://erinkissane.com/mastodon-is-easy-and-fun-except-when-it-isnt is a good overview (not by me!) of issues that the November 2022 wave ran into. What's frustrating is that so many of these are very similar to the issues the April 2017 wave ran into!
Release 4.3 did some work on the recommended accounts, that's good, but the problems start even before that. What instance to sign up to? Most people have better experiences on smaller instances that match either their interests or their geography ... but how to find them? mastodon.social is (for most people) kind of meh -- certainly not the worst, but it's not all that well-moderated, and it's big enough that the local feed isn't useful for finding interesting people or stuff -- and that's now the default. Also it took over a year to get 4.3 out; I get it, they're a small team, some stuff turned out to be a lot harder than expected, and they had to deal with a bunch of security patches in the interim ... still, that means progress is frustratingly slow.
This bill can't pass without Democratic support ... but last week, over 50 Democrats voted for it! It didn't quite pass, but now they're trying again ... so please, if you're in the US, please call your Congresspeople!
