The context of the link and the intended audience (go contributors) are not obvious within the context of a link posted to HN. Sure, you can read through it and look around, but most will read the initial document with their own mindset and experience, so a lack of context is problematic.
I can see how lack of context is problematic for people who simply must share their opinions without delay.
But even without the context, your comments are in response to a misreading of a very small part of the overall document. Hardly seems worth your time.
