> I really don't see it as a forum for ideas or activism, unlike Twitter or reddit. but maybe that's just the bubble I'm in.Exactly -- and that's the real danger of algorithmic engagement-driven content.
For you, it's picking harmless content because that's what you engage with. But once you start engaging with, say, some crazy cult, Facebook's algo will pick up on that, and start prioritizing content from the crazy cultists. In time, you'll get to the point where you're only seeing content from the cultists, and come to believe that's what everyone thinks, because that's all you'll ever see. YouTube suffers from this too.
