Turns out Zoom actually runs on Linux in addition to Windows and Mac. But I'm still not a fan; I would run an audiovisual calling program that was FOSS as my first option or, if not that, using WWW standards.

Watching that '80s TV show about a band going by "Holograms". I first got curious about it back in 2015 as a film originating from that show was first shown and a lot of folks said it wasn't faithful to original. It was in Crimson N's film and TV library but not now.

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.
