Mastodon has been much in the news lately as an up and comer alternative to Twitter. Time will tell if Twitter can survive the erratic behavior of its new owner. That said, Mastodon is still a good idea. It is decentralized, meaning that you join a particular server (or instance as they call it). Think of it like joining a community group. You join the local chapter of a much larger organization.
In my case I joined a Canadian server mstdn.ca which seems very well run and is supported by CIRA the Canadian Internet Registration Authority. As of this writing most of the major news organizations have Mastodon accounts. Since I use Mastodon as mostly a news feed that suits me fine. If you are curious there are many good videos on YouTube to get you started.
It’s hard to tell if Mastodon will take off. I’m going to give it a try and we’ll see.
