Maybe you had no idea but what you describe already exists in the form of native ads and recommendation widgets like outbrain. And here's what I do when I run into them: I rarely click them. When I'm on NYT, I don't want to click out to some "recommended" website that doesn't have high journalism integrity as NYT (Let's not get into a needless argument of whether that itself is correct or not). My point is, I disagree with your argument that "different source" has anything to do with serendipity. Also you say silo shouldn't exist but I don't see a reason why. Sure there are clearly cases where certain companies siloing up their user's data is bad for humanity, but in this case it doesn't even make sense (what even is "silo" in this context anyway?). People create silos because of demand. Imagine if NYT started opening up and let any random guy on the web write articles on their front page, what did they gain by "opening up" their silo? Most readers of NYT are there exactly because it's a silo that guarantees certain degree of quality. Once they start "opening up", you'll probably be the first to say "yeah New york times is done now, it's all low quality now"
