I was not at the virtual meetup yesterday, so I can't speak to the quality of that. But I have been involved in virtual-only meetups with other LWers. Aaron is right about not having critical mass, but to the best of my knowledge there's still 3-5 of us in my group who aren't currently meeting* but would be potentially interested in doing so.

*Mostly due to us all being too busy to prepare and run a single topic/workshop, and without that the social interaction is pleasant but not quite good enough to make time for
