My comment was posted when this page had no comments, nor was it on the front page. In fact, I think it had less than 3 or 4 points. I was just informing the original poster, given that I too thought it was an interesting article, that it seems there was little interest here on HN.

Clearly, due to getting enough karma to put it on the front page this time, my comment is indeed now irrelevant. The post was clearly just missed the first time as you say. Whether this is a problem with the karma/new post system or not is a different matter - and probably not one for discussion here.

I didn't think I'd get downvoted though, given when my comment was made, but your points are fair.
