FB employs one of the world's best C++ developers (Andrei Alexandrescu) to write custom string implementations and maintain/extend their homegrown PHP VM. Their development practices would be completely unsustainable for any company that has anything resembling economic accountability.

Ah, many companies have homegrown languages they use internally. You don't even have to be a big company to do so. Wasabi is an example of that.

True; I just disagree with the general tendency to treat everything FB or Google does as the holy grail of best practices (or even good at all) for the average company.
