Search for example on "deep learning". Results: + nice: open books (deeplearningbook.org) + not nice: online seminars (udemy, udacity, edx) + not nice: wikipedia copycats (investopedia) + not nice: SEO optimized business analytics sites recognizable by their top 10 this, top 20 that (kdnuggets) + not nice: commercial software (mathworks) + not nice: big companies hitchhiking on buzzwords (sas) What would be nice are websites and people that are often linked from HN. For example http://www.inference.vc http://www.inference.vc rather than sas. Or https://distill.pub/ https://distill.pub/ rather than investopedia. Or https://www.tensorflow.org https://www.tensorflow.org rather than mathworks. If good sites are showing up in the top results more often, there will also be more incentive to keep up the good work as well.
