The thing about somebody out there always disagreeing with any position or opinion you post and nitpicking details is certainly true, and can be disheartening, but framed another way it's awesome training for improving your written communication. Being able to post anything you like and never having anyone nitpick it would be a little bit like playing tennis with a friend who is much better than you but goes very easy on you and still lets you win. It might feel good, thinking that you're always hitting winners, but you're really not. And you're not improving. Look at the best comments and commentors here and on places like twitter. What makes them good? It's that they make their points extremely tersely and unambiguously. You can disagree with the point, but you can rarely nitpick or 'well actually' the way in which it's made. It's frustrating sometimes when people do this, you often feel like saying 'you know what I mean by that' - but the truth is people don't - you've been ambiguous and communicated the point not as well as you could have. It's frustrating, but it's actually pretty good training to learn from these nitpicks, because clear, terse written communication is a really important skill that's useful in a lot of places in life outside of discussions on forums like HN.
