Even though this is old, I'm glad it's here again. Jessica deserves so much credit for the success of YC but she's far too humble to make a big deal of it herself. It's important for the rest of us to call this out once in a while. Thank you Jessica for everything you've done and do.
It seems to me that one reason for her success is that's she's able to exist in the limelight. Give her a higher profile and I'm not sure that the her approach as described in PG's post would work as well.
I'm not convinced that everyone wants much attention - I know that I don't.
