> Valve has an amazing culture, but I'm not sure it would scale to a 50,000 person company

This reminds me of just a few years ago when I was arguing with someone about this, when 37signals was in their infancy and were kinda trucking along with the same 'bossless' philosophy. I was trying to show that it could be successful and the person hacked me off at the knees by saying "come talk to me when they get to 100 employees" ... well Github and Valve seems to be doing just fine with that philosophy ... but now the goalposts have suddenly shifted.

I wonder if they get to 50,000 people (how many companies even have this many people anyway?) if somebody isn't going to pop up and go "50k people? pffffft ... come get me when they have 200,000 employees!"
