It always bothers me when I read something like this - I strongly disagree. There's always going to be things that are tangential to what can be considered HN's main "scope" - I'll go on a limb and say the main scope here is programming and entrepreneurship. Writing (and communication in general) is a key component of what makes an exceptional coder/entrepreneur (or professional, to generalize). So I do think this is a great post to see on HN. And lets be honest, there's a ton of other good posts to read on the homepage right now if you do not like this one - thats what makes HN pretty darn good.
