I've never been to a nest. But I always like to be in contact with my conversation partners. Ideally, one person. It's also nice if I can see facial expressions and gestures. I think in a discussion group like the nests, you also can't see when someone wants to speak and how what is being said is being received. This creates confusing conversational situations. I also enjoy 121 conversations. But nests are of course also great opportunities to make contact.
