I see a lot of people around me using Mastodon, but I've yet to actually try it myself (I don't really like social media). It's federated and you can run your own instance.
I've just tried Mastodon recently and haven't been blown away by my experience so far, but I don't like social media either. It's more a Twitter replacement than Facebook. I'm looking to get out of FB as well...
Could you elaborate on Mastodon? I've been following it for some time, wondering whether it's worth the effort to join? (And try and drag some of my friends along as well ;-) )
