I've been here a week or two now. It's going better than Voat did for me when I last tried to leave Reddit. That was full of alt-right crazies basically, but so far here, people have been lovely.
This seems like the first thing with enough critical mass to get going, what with reddit and twitter sulimultaneously imploding faster than a poorly constructed submersible craft. It's not driven by political outrage so much as the old platforms making themselves unusable and forcing healthy users off their platforms.
