Definitely don't hang out on Hacker News then. It's absolutely the worst place for imposter syndrome or people with any kind of skill inferiority anxiety or confidence issue. Half the reason I read HN is because the anxiety it induces is moderately constructive in motivating me to ensure I keep learning and stay up to date. But I definitely come away every day with a distinct impression I'm below baseline in skill and knowledge for my field, even though within my own circles I'm considered expert by all my peers.
