Sometimes I think more the toxic people who wrote about politics and identity on Mastodon moved on to Bluesky when Trump got elected.

I don’t see why it is “zero” sum, nothing stops you from posting to more than one social. I mean, I have relatives on Facebook and no prospect for getting them to change so I cut-n-paste what I posted on Mastodon to Facebook, Bluesky, LinkedIn, Tumblr, and all sorts of places.
