And yet... asking us to sign up for Board Game Arena and Discord is exactly what the weekly game night I've been involved with the last month did, and they have 8+ people every week. (For that matter, I asked the folks in my new D&D campaign to sign up with D&D Beyond and Discord, and that went fine as well.)

That's fair, I guess depending who you play with, some people may not have a Discord. You do have to have a Discord account, correct. All of my friends and I are already all together in a Discord server, so it makes sense, but if it was new people playing that could def add to the hurdle.

Jit.si is as easy as https://meet.jit.si/joemasilotti Just give browser permissions and you're in.

Vast majority of people IME already use Discord for many things anyway

"Gamer" community bias, IME, as well as other internet-age communities.

It's not the most general platform, but it's one of the best at what it does: voice and text. Video is just icing on top.

If Discord had a version suitably branded for Business, I'd say it'd be better than Zoom and Slack combined.

It just works.
