This is more for reddit than hacker news (although i would say hacker news is the same to a lesser degree). More and more I've been feeling that all that exposure does is make one feel like one is learning a lot but in reality its just a wide shallow understanding not really useful for anything. It's good to gain exposure but its easy to fall into the trap of mistaking exposure for thinking real hard and working to understand something deeply, at least that is how i feel.
