I also feel overwhelmed while reading HN. Being surrounded by so many great and smart people, I feel like I know nothing and like my entire career until now was a waste of time and resources. I am also becoming addicted to HN. I left Twitter behind and now HN is my primary source of information. I am reading HN anywhere: in subway when I commute to work, in car while I stay in traffic jam, before I got to sleep, at work, etc. Thank you all for making HN such a wonderful place.
