It has the opposite effect on me, I barely open facebook anymore because of how irrelevant it is and I skip the landing page on YT and just search what I'm interested in.
This doesn't require algorithmic feedback loops. People simply would seek out (and create) content which provides inconsistent rewards. A slot machine simply needs a random number generator with a certain small chance of jackpot. The null model here is what can be achieved without individualization.
I'm not sure "randomness" is the general property, but rather unexpectedness. The content-provider may well be following a "formula" like with fiction plots, that give the protagonist setbacks and victories. Facebook uses approaches which try to profit within the constraints of a relatively small group of programmers trying to make money off billions of users. It doesn't mean these approaches are the best overall at serving the most desirable content to any given niche of users. Or even the best at making money qwithin those constraints. If are to believe in "network effects" (the other popular basis for calling for a breakup of Facebook) Facebook is simply succeeding because it is there first. Rather independent of this claim that they are winning by being the most competant.
Dono what's with your strawmen arguments here or what your point is besides being argumentative, but I didn't say anything about best. I'm gonna just assume they all see some value in it and you don't have any inside knowledge.
The point of the thread is that these algorithms are not a special new threat, but it's the availability of content itself, targetted or not.
Since we're analyzing each other's psychology now, I do think that insecure and defensive behavior like your post is a real problem with social media. I am not trying to bully or hurt you personally, but simply share some thoughts on a topic.
