Bluetopia
I try to imagine how Bluesky looks after it scales up to Twitter size. I discuss how aspects of its architecture lead to big differences in how far different elements can diversify, and how this leads to predictable outcomes of how they respond to commercial pressure. I judge the overall result as feasible, and better than the status quo, but complicated and fragile. Finally I suggest how cooperation with the Fediverse could look, and how that is a more promising outcome.
