I think only the platform can fail at disappointing their users in discoverability. The one mistake is valuing followers over substance. In Subreddits, for example, you can provide value without requiring social proof in the form of followers. Ironically, the best accounts on X are often between 739 and 10.142 followers. Beyond that, most accounts maximize for engagement and value drops. There should be no incentive to maximize followers. Instead, there should be an incentive to maximize "value provided". Nostr has the feature for zapping microtransactions. Medium - I believed - tried to achieve this by allowing you to "heart" an article multiple times. The number one metric should be value provided measured through: "time spend reading" an article, the amount of collected $, the amount of bookmarks, etc. Following should become a much more exclusive feature that either costs $ or has other psychological barrier (i.e. you receive ALL posts as an email or notification) so you choose carefully who to follow.
