I have found, in general on HN, that snide comments, even if you think they contain a grain (or nugget) or truth, with be down-mud. If you have a point, make it clearly and carefully.

My advice - you you choose to accept it - is to be clear, concise, and more complete. Snide doesn't work here, as your experience should already have shown.

Well thought-out - if negative - comments rarely get down-mud. Your original appeared to add no value.
