There is one person I follow on mastodon dot art, that I would hate to lose touch with.
By contrast, I follow over a hundred accounts on kolektiva dot social, and many of them I rely on for news about radical organizing.
When I decided to move from my original instance -- because of frustration with bigotry in moderation decisions and a refusal to take process seriously -- social dot coop and kolektiva dot social were my top choices.
In part, I thought anarchists should spread out a bit.
