I think I would be fine with a positive enumeration. Some ideas for serving content:

    - purely random
    - sponsored but without user tracking (like old school TV ads)
       - sponsored for user selected geographical area feed
       - sponsored for user current location geographical area feed
    - follow "friends" or influencers
    - purely timeline

    - discussion boards
      - timeline (IRC like)
      - threaded
      - user votes (not magic platform votes)

    - follow keywords

So Hacker News wouldn't be allowed?

I think it should be, maybe I'm missing some aspect, I just cooked up a simple list of rules on the spot, sheesh :-D

Edit: huh, I'm probably stupid, but can you explain more?

HN uses magical platform votes.

And it should be transparent about it. When Dan uses a magic lever, it should be visible.

Would Facebook be okay if all the Nazi propaganda posts were tagged "Facebook boosted this post"?
