Well, that's quite sad to hear :(.
This is truly an end of an era. I say that because actually, all the alternative chats don't quite the inclusiveness that draws in the new blood to create the community it became. A Discord chat, which I've heard numerous suggestions for, would honestly just attract a very narrow demographic. It would not attract the 'passers-bys', who can just drop in within two clicks. These are people who are retreating to some niche corner of the internet, these aren't people selecting one of several channels for the intent sake of making use of some trendy VoIP application. On the chat, I've seen:
People's deepest neuroses
People's realisation of their hopes
People's realisation of their regrets
People meeting up
People getting married
People losing touch.
People abandoning statism and embracing anarchism, championing libertarianism
People abandoning anarchism and embracing statism, championing the alt-right
People naively encountering @Tundra with an ethics debate, with great pandemonium.
Good times. And perhaps for the time being we will use the prop-up chat @CaveWoman posted here, and perhaps I will make an effort posting here for the sake of touching base with the community that raised me for quite a long while.
