> All the recommendation algorithm driven platforms tend to encourage active posting and discourage occasional participation.

This is an important point that is not mentioned enough.

The problem whenever a platform introduces an algorithm to decide what users see, by either promoting or penalizing submissions, is that it unavoidably leads to content that is created purposely to game that algorithm, which ultimately corrupts the user experience.

This happens not just with social media and video platforms, but with web search results as well. The vast majority of web content is now spam whose only purpose is to generate ad revenue. SEO is a more accepted practice, but it really shouldn't exist at all.

For search results there obviously needs to be some algorithm behind it, but this should be driven exclusively by delivering the most relevant results, and the only smart behavior should be spam detection. Google had solved this decades ago, yet they've created a global problem they can't, and likely have no interesting in solving. As far as investors are concerned, it's a legendary success story, and that's all that matters.
