I can see how HN is bad for the author's well being, but certainly not for mine. I don't feel bad about reading other people's success stories. I don't feel any need to switch languages/frameworks when reading about new/hyped stuff. It's all just information, what you do with that is up to you.
Sure, but what is the opportunity cost of reading all of those posts and what are you really gaining from reading all of those "new technology of the month" postings?
I'm development lead on my startup and just being aware of new tech, other startups, problems with frameworks, algorithms,... all help me be better informed for my job.
