@phooky Word fact: don/doff is a corruption of d'on/d'off, which is just a short form of "duds on"/"duds off". (not an actual fact)
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.
