I am involved with 2 ongoing zoom buddhist meditation groups.  One
involves guided meditation followed by discussion.  The other is
just open discussion with a teacher who is answering questions. 
These are wonderful.  It is great to visit with other teachers and
practitioners all over the world.  For me, an open discussion with
zoom is much  more helpful than hearing the same thing in a podcast
or on youtube, because I can interact.

Can anyone here point me at other zoom meditation discussion groups?

Dhammarato has an online sangha via skype. Think it's a weekly thing.
You can find more info via his youtube channel "Dhammarato Dhamma".
