The purpose of flagging is to indicate that a story does not belong on HN. I think I've explained why I feel this is particularly a low-quality submission, and flagged accordingly.

I don't see how you can think that is selfish or petty, unless you think having yet another thread to just complain in is actually helping anyone.

Either way, I don't want to get into an argument here (obviously), so I'll pop out of this thread now and leave my flag behind. If people want to vouch it out, that's fine too.
