Baffling that you mention the guidelines when your blog psot (although not submitted by you) had a tremendously link-baity title and had little of interest to say.
The "not submitted by me" is the key point. I submit my own posts when I think they're of interest to HN. I have zero problem with people downvoting or even flagging a post that doesn't belong here.
But when we comment on the post, we ought to follow our guidelines. As you did, you were able to criticize the post without being rude, mean, or nasty.
