Surprisingly, I agree with my co-founder. "Hacking" the yc application process implies that the poster was able to put much less work into the application than others did through cleverness on the poster's part. The post sounds like he thoughtfully filled out the application in a way that highlighted his strengths and minimized his weaknesses, as everyone else does. He also put a lot more work and thought into it than we, and the other yc founders that I know, did.

Instead of building that application for a whole month, he should have been building his product and landing customers.
