@digitalthan I was just playing with that, comparing it to Amaroq. Didn't find anything worth switching for, and cutting up cat photos is a big drawback!
Mastodon is a "FOSS" social sharing hub. A multi-host substitution for capitalistic platforms, it avoids risking a particular company monopolizing your communication. Pick a host that you trust — you can still talk with all hosts running Mastadon. Any individual can run a Mastodon instantiation and join in this social hub in a jiffy.
