The assumption is that centrally managed social media is bad because their algorithm is bad. But actually, they are bad because they are centrally managed and force one algorithm onto you. I’m not even advocating algorithm-by-choice. Even instance-specific algorithms would already work and would make the whole experience much more enjoyable and less boring. And if an instance’s algorithm(s) is too aggressive, it gets defederated. That would result in a much more exciting experience imo. And by the way: what’s the problem with getting old posts back in the timeline if it makes the overall conversation more interesting?
I guess one issue about engineering a well performing algorithm is that ot only works if you collect a real high amount of personal data and label it with stereotype based labels. And then you have to do the same with every content shared on the platform.
If you do this publicly, people will have problems with the labels of their posts.
Your awesome idea gets labeled as left wing utopic dream? Your rant about that new movement is conservative and populistic?
Might be true, but will offend people.
