I was talking about the second part of the equation, i.e. taking it into account on the hiring-decision side. I know refer-a-friend schemes are common, but I think most companies (including Google?) don't give any weight to the fact that someone referred a friend. In fact, considering the incentive structure (you get lots of money to bring in friends), companies shouldn't take into account recommendations. It would have to be done differently in order for the recommendations to actually mean something, which I'm guessing is more common in startups than large companies.
