I don't think anyone is applying for the money. After all most people are in their 20's with little to no responsibility. Just living in the Cambridge area for the summer will eat up a chunk of money. If you have a great idea and must have 3 months to concentrate on it or you'll never get it done, just move in with the folks for 3 months.

I think most people are applying for the mentoring and collaborative environment.I found a great partner in the process. That has to be worth taking the time to apply.
