I didn't downvote but you may want to read HN's Guidelines[1], particularly: Resist complaining about being downmodded. It never does any good, and it makes boring reading.
The challenge (no complaint here, though I do believe it was down(modded?) merely because of disagreement and not for relevance or quality) was meant to incite more on topic discussion.
It's interesting I've never read the guidelines before now. Was refreshing to have taken a look, although it's mostly common sense and etiquette.
