A large number of comments here looks like every employee at Facebook is exceptionally skilled and critically important. I read somewhere only square root of total employee strength are doing critical work in the company. Now I do not have any proof of this but I am working at company which would have may be 5K work force in IT organization. Here I am regularly surprised that hardly 10-15 names out of 100s pop up every time on any important issue for projects which I have some relation with. Doing same analysis with facebook would mean there would be 250 or so employees who can seriously negotiate salaries with them for being critical to company. Of course some people would get lucky or unlucky despite being less or more important. But I think this is delusional to think that most of ~50K strong workforce in FB will be able to get their compensation demands like bay area salary in middle america accepted by company.
