Except when it isn't. Like the confusion of a name, claim a name, channels, requirements to meet some bullshit before you can speak, and chat in which area and all the while it looks really awful.

I did basically the same thing with someone today, I sent them a link they clicked and we started chatting with Jitsi.

Realistically the issue is creating the place to go, not the service itself. That is the more difficult part.
