@buckE First off, welcome! Mastodon simply explained is pretty much Twitter, but takedown resistant, with more useful choices (including instance and client), and much more private and secure. Its the only "social media" platform that I use, and I think it's pretty great.
@ThreeBadgersInATrenchcoat Thanks! I don't know what Twitter is (I mean, I hear the word but that's all) but I like "private and secure." What do people do on Mastodon except talk about Mastodon? :)
