On twitter, facebook, etc you follow people. Then the algorithm creates a bubble where you only get opinions and points of views you “like”.

But when you use reddit/lemmy the algorithms are based on popularity , which makes it vulnerable demagogy and other cognitive biases (like the tendency of the human mind to be a cognitive miser).

If a chain is as strong as it's weakest link, it is better to use multiple chains, following users allows following people who are experts and extremely knowledgeable (andrew huberman for example).
