The problem is that there is way of the developers to filter the companies - I don't want any company to be able to see my CV, I want much more info and control, if I am to pay (especially that much money) I want better service, uptime guarantees etc (I can't look a gift horse in the mouth, but only a moron will buy one without looking well at it) - and the Stack Overflow team will never go for that.
