To be fair I am truly surprised at the comment thread here and people being surprised that it collapsed and the lack of understanding of magnitude of forces. I always think of HN as a fairly educated group with a large portion of engineers (skewed heavily towards software which doesn't always have a background in the physical environment).

I don't intend to sound pretentious or condescending. Maybe its more that I need to reconcile with my own expectations of the community level of knowledge/domain of expertise.

I rather have a high bar of expectations than a low bar though to be honest.
