you don't learn a lot from YC, you do from HN content, they use their userbase to promote their products
we, the users, are the ones responsible of you "learning a lot" by submiting content, and reacting to it, therefore take my suggestion, since i contribute to that too, if you wish to "thank the people who make you learn a lot"
educating people, that's what i am trying to achieve, whether you understand or not, i won't stop
