I didn't submit the post to HN, nor did I choose the headline (which I disagree with).
I'm aware the recruiter in question can't change anything, and have no hope of it having any effect at Google. Maybe it'll prompt readers to put their thinking caps and go further in their own reflection about their life and career. And that's all I'm asking for.
I'm interested in your use of "uninformed" though - to the best of your knowledge, is there anything in that blog post that is factually incorrect? I'll happily correct it, as long as it's backed by sources.
If they even got one paragraph in I'd be surprised. Delete - next candidate.
Fact is, it's an open letter, and therefore guaranteed to connect with his target audience who are not, in fact, google.
