Anyone know what the "bottlenecks" are in YC? I assume it has to do with the number of advisors? Also, I wonder if the growth in number means decrease in quality (or experience) for the entrepreneurs.
The biggest bottle neck is quality applicants, if I remember correctly. I believe PG mentioned that Y-Combinator could triple in size and not be severely affected, though.
Although that might be the first bottleneck YC probably cannot remove, the bottlenecks PG talks of in the OP (such as office space) are the removable, short-term ones that prevent YC from immediately tripling in size.
