The implication of 'be awesomer' is of course that what was written in the applicaiton is already 'awesome', at least in the mind of the applicant.
However awesome you think you are you need to appear more awesome than that to get into Y.C. :-)

I think the same approach would be useful for a YC application. Get other people to critique it, and iterate and improve. The trick is picking good reviewers. Probably more people can review copy than a YC application but I hear YC founders are generally friendly and like to help.
I recently made the mistake of doing a rush application for my local TedX and didn't get picked for the audience. I should have applied the "awesomer" philosophy to that.
Now I am going off to work on that robot...
