This is not how criticism is done. There is no constructive comment here. There is effort involved, and this person is attacking that effort.

Not even going to bother replying to the original poster, but thanks for recognizing. Just have never seen anyone on HN misconstrue feedback so badly. Doesn't bode well for their ability to adapt and succeed with a product if they take genuine feedback (corroborated by several others in this thread, mind you) as not constructive and dishonest.
