@vinnl It seems cool, but I'm not sure it'd work. I thought about this because one of the problems I've noticed in virtual conferences is that after the main "talk", some people start talking but it's only one track. What's nice about physical conferences is that after the talk, groups of people form organically and you can enter/leave those group conversations easily. Maybe that wouldn't work in a virtual environment but it was just an idea I had :).
@noeldemartin That's definitely an experience they're trying to recreate: walk up to a subgroup of people and start a somewhat private conversation, while being able to walk over to a different group of people to switch conversations at any time. The two main things missing IME are seeing facial/bodily expressions (though the latter is supposedly possible in VR), and recognising people.
