I have a friend who hosts a Zoom room (used mainly for tabletop gaming) and another who runs a Discord server (used for CoH and other MMOs).
I love 'em both for doing it, but both applications drive me nuts!
Zoom has a terrible interface, is wildly different across platforms, and has ongoing privacy and security issues.
Discord has a terrible interface, ongoing privacy and security issues, and unique technical aggravations.
(I run and recommend TinyWall, a small add-on to Windows firewall that blocks any program from accessing the Internet until you approve it. Most programs, including frequently-patched ones like Firefox, require only one initial approval. For whatever reason, Discord needs to be reauthorized every time it updates. Which it does every time you launch it!)
And, yes, both tend to have at least one participant who hasn't spoken to another human all week, and just wants to chat.
