Good curation is amazing.

When I first signed on to Netflix it worked me out and suggested a bunch of stuff that I love to this day.

But then it ran out of stuff, or they borked the algorithm and now it sucks. And all its competitors suck.

One thing I have noticed is that if you ask a human for a specific recommendation like "Suggest me a novel like The Martian" if they dont have a specific recommendation, you just get their favourite instead. Which makes reddit threads and similar completely useless. The signal to noise ratio is awful.
