I'm not a psychologist, and I don't know you personally, but is it possible that maybe you feel a bit misled because you think you might be missing out on some great riches that everyone else is claiming to be achieving?
I think that, at the end of the day, everyone has a bullshit detector, but everyone's bullshit threshold is going to be determined by how close they are to greatness (whether they themsleves are achieving it, or the people around them are achieving it). For me, HN represents a rare intersection of do'ers and dreamers. Are all the people who claim to be "doing" actually doing it? Of course not, but there are still valuable lessons here. There are enough lessons in Patio11's posts that even if he were exaggeratting his claims to promote his brand (and I don't perosnally think that he is), I'd still consider his contributions to be worthwhile reading.
Skepticism is a healthy thing in moderation, but I for one, would rather be surrounded by a lot of people who are optimistic (if a bit boastful), then a lot of people who are pessimistic and critical, but I'd trade them both for genuine friends with efficacy and cogency.
