What actually happened to the ideal of rewarding content based on 'attention minutes'? My experience of Medium is that the content that gets surfaced is from people who are already 'notable' in some other way (think that Medium allowing you to import your Twitter followers and have then auto follow you on Medium doesn't help this), and low value Steve Jobs self-help bullshit. I can buy into curating 'hidden gems' using data in the way Spotify does, I can get behind breaking unheard voices, but I can't see how the current model of giving famous people a megaphone was ever going to upend journalism.
