I'm curious because this seems to vary greatly between companies - what is the difference at YC between the roles of CEO and President?

From the intitial announcement of Michael becoming CEO:

* Michael Seibel will be the new CEO of YC Core, which we are now just going to call “YC”.

* I’m going to be the President of YC Group, which includes YC, YC Continuity, YC Research, and our new online class. We’ll add more organizational units over time.
