"Do you think that Zuckerberg is the best developer at Facebook - legend may say so but it's not true"
What is this legend? I think everybody is aware of the fact that the infrastructure that allowed facebook to scale was not (and probably could not have been) built by Zuckerberg. He had guys like Adam D'Angelo working for him from the beginning.
The employees of tech companies with charismatic leaders sometimes elevate their Great Leader to legendary status in their field of expertise, whether its true or not. Worshipping is part of the tech company cult thing - you do see the parallel of course with cults and tech firms? There will be plenty who believe the Zuck is the best coder there or amongst the best at least.
He's more like the Bill Gates of the company. Has serious technical chops, and knew that technical thing like scaling were not optional. Compare to the object lesson of competitor Friendster, where the people running it after they ousted the computer programmer founder ignored that minor detail....
