It bothers me when people try to tell businesses how to improve their operations, purely for personal benefit. The point of VC firms is not to fund your business, its for VCs to generate a return on investment. VCs surely know that by not reading all of the applications, they are missing potential winners. But they also know that getting strong introductions is a much much much more efficient way of finding potential winners.
It is not the system's job to work for you, it is your job to play within the system.
