Things like this DO NOT MATTER. Facebook was built on PHP and MySQL, both of which are awful pieces of crap. Twitter went down like every week for a year. It was written on RoR by people who didn't really know RoR. Meanwhile, a bunch of better engineers using better technology got their clocks cleaned while the winners eventually had so much money they could afford to hire an army of engineers to rewrite everything. If you know Javascript really well, use Node (although I feel sorry for you). If you know Python really well, use Python (yay). If you don't know anything, well, pick something. If you are choosing a programming language because of how many QPS you can get on some trivial task, you are an idiot. You know the graph I would like to see? A scatterplot of how good various startup founders and early team were on engineering vs finding a market fit, with the dots labeled with how rich they are now.
