> (1) ban all recommendation engines in social media, no boosting by likes, no retweets, no "for you", no "suggested". you get a chronological feed of people you follow, or you search for it directly.

I always find these comments interesting on Hacker News. The Hacker News front page is a socially sourced recommendation engine which presents stories in an algorithmic feed, as boosted by likes (upvotes) from other users. The comment section where we're talking is also social at it's core, with comments boosted or driven down by upvotes and downvotes.

In your proposed regulation, are you really expecting that the Hacker News front page would go away, replaced only by the "new" feed? Or that we'd have to manually sign up to follow different posters?

If we have to sign up to follow specific posters, how do you propose we discover them to begin with?

Usually when I ask these questions the follow ups involve some definition of social media that excludes Hacker News and other forums that people enjoy.
