I wrote something about how I'm judging people who joined BlueSky, and I've since had a number of Black friends reach out and explain to me why they feel more hopeful about finding safe community on BlueSky than in the Mastodon-centric Fediverse.
So, my judgment was unwarranted. As reluctant as I am about the business model of for-profit social media companies, I also see how little has been done to make Black folx feel welcome here. I've definitely run into the nitpicky / tone-policing aspect of Mastodon, and I barely posted on here.
