Actually yes, I have written a recommender system.But if there's 1 thing I've learned over the years is that you don't go overestimating the complexity/intelligence of any system unless you take a peak underneath. For all you know, Hutch could be just hiring curators with good taste rather than write some complex system that would need to be constantly changed and updated. But people have all the incentive in the world to "over fluff" and overcomplicate their work to make it sound valuable. It's smart, but you gotta be skeptical.
