@daringfireball interestingly, in non-shitty Google, the 1st result for "how many rocks should I eat", excluding Quora (possibly says something about the quality of answers there?) is for a company called ResFrac... who specialize in "hydraulic fracturing and reservoir simulation solutions". Specifically, the result is a blog post, which is... a copy of the Onion article!!

The language used on site (and the use of The Onion article) makes the layman wonder: is the company legit or a spoof?!
