For some reason all of this induces negative emotions in me as well - it's like everyone and their mother wants to tell you how excellent they are and how you should live.
Maybe it's this "write! you need to write! now!" advice which is frequently appearing on HN frontpage, maybe this is the reason why programmers with two years of experience are telling with authoritative tone 'how it should be done'
It's annoying to try to filter out "fake it until you make it" lot but I'm afraid that there is no solution besides big dose of skepticism
