The reason “low-effort” posts get more views/attention than “high-effort” ones is that humans have a limited attention span and everything is trying to grab it (ads, your phone, etc) to extract money out of it. Committing an hour of your life to watch a long high-quality video and learning something from it requires a lot more concentration and willpower than watching 60 1-minute short videos and laughing at each one - and ad interruptions are not as noticeable. It’s not necessarily a bot problem, more of an attention span/capitalism problem. This will also be the case in the Fediverse, to some extent, although likely less because there’s no monetization incentive.
Cool!
However,
