Zoom is said to be easy to use for voip, but I found discord to be vastly superior in terms of ease of use and config.

Basically all the ceremonies and friction of the networking aspect and video/audio aspects are gone.

Now I think the community model of Discord isn't really in congruence with the knowledge base model a la Reddit(its hard to drop-in and out of community just to get one answer), but it is still vastly superior to its competition.
