Halfway the this post, I realized checking the HN front page was merely a thin desire – so I'm off to read a book. Farewell!
Like relationships I don't think it's either/or but rather prioritize. Make the book a priority, and make sure you do it, then go ahead and read/comment on HN. The extra knowledge/perspectives/experiences will make your contributions more valuable for everyone.
I have bad news for you - you're not even just "checking" HN, you're simulating social interaction by writing comments for no one in particular.
Just thought this as i glanced your post. See you later!
