At some point it will make sense to start thinking about YC as a staid financial institution (whether or not that point is today, is another question) rather than some plucky newcomer. The amount of money an organization has affects its operation. It's impossible to spend $1 billion carefully deliberating $20,000 decisions one at a time...and carefully deliberated $20,000 decisions one at a time was what made YC successful...and how and why it changed the startup landscape.
