My nightmare has finally come true.

Ok, but please don't post unsubstantive comments to HN, and especially not shallow dismissals of someone's work.

Sorry for the judgement of the lack of "substance" of the comment, but to my defense I see this kind of comment all the time under almost every post (including this one), and it is not always obvious unless pointed out.

And this is in no way dismissive of the work. I can definitely see the value in this -- I am just saying many people don't wish to see this, which many people apparently agree based on the number of votes.

Yes, too many people post that sort of unsubstantive comment—the cheap one-liner is maybe the biggest forum cliché there is—but that doesn't make it ok.

I believe you that you intended something more thoughtful, but the rest of us don't have access to your intention (or the real meaning of the comment in your head). We can only go by what you actually post, so if you want to make a more thoughtful point, you need to do so explicitly.
