If you still have legacy social, agitation over there is doing rounds right now. Unfortunately, there’s significantly fewer of us working to get people onboarded than the last migration. If you still have those accounts, please consider plugging fedi.
One possible group on Reddit to reach out to are the people doing /r/50501 - they’re organizing a large protest on Feb 5th, but it looks like a continuing resistance movement. They have more visibility on platforms outside of the Fediverse, but it’s only a matter of time before those platforms begin to throttle their visibility.
If they also grow a 50501 community on the Fediverse, when the throttling inevitably happens and the news pays attention to it, both their movement and the Fediverse will get a boost. They’ll probably lose their ability to organize on Reddit, but they will win more followers and help develop a better social media system.
If they promise not to link back to Reddit, I’d like to host them here.
