I did something similar, but with current youtube search results and not really stress processing on HN data. My technique was simply saving my search terms and topics, and then putting that under a crop and continually updating the results. Super simple, but resulted in such a better experience for YouTube videos for me.
I call it "re-algorithming" your data. Basically you're not happy with the algorithm of a product, then you use it's data and introduce your own.
It also seems like folks are tired of the youtube algorithm and want something different instead? I'm willing to bet that many sites and apps have this opportunity in them.
