One I'm personally a huge fan of is Mozilla Hubs (https://hubs.mozilla.com/), which is 3D and VR compatible. It's not accessible enough to people today, but it's very, very impressive!
And MakeSpace: https://makespace.fun/
And GroupRoom: https://grouproom.io/
Used it for a few 1:1s and sprint plannings. I love it!
But gatherly doesn't seem ready to serve my family and I if I have to request info (I can't just sign up).
What's the best, simple app like this that allows easy subconversations that my family, parents, other non-technical folks could easily join?
I don't mind paying to host but it has to be easy for them to log in and use.
I personally don't find virtual stuff fun, the pandemic is really sad, so wanted to make something available for public use. :)
