It feels like a hybrid between chat rooms and group threads like we have here on SG. Topics within someone's server are divided into their own channels - so like one channel for selfies, one for food discussion, one for music, one for mental health, etc. - and you can click on any channel and comment away and reply to other people. There are voice and video chat options too. And the server owner can stream stuff so that we can eventually have movie nights. And so on.
