I'd just like to interject for a moment. What you're referring to as Mastodon, is in fact, the Fediverse.
@oklomsy Mastodon on its own is not a fully functioning micro blogging platform, rather a vital component of the fully free fediverse system
A instance dedicated - but not limited - to people with an interest in the GNU+Linux ecosystem and/or general tech. Sysadmins to enthusiasts, creators to movielovers - Welcome!
