Although I was initially against it, having another "round" where partners narrow the list could allow for a number of questions to be answered. Most of these questions could not be addressed in the 2000 character limit of the initial post. These questions include things like whether or not the applicant(s) have the ability to complete the project, what is their domain expertise, have they worked on the project on their own, what is the market size, how are they better than the competition, can they explain how the idea is really a worthwhile company and not just a neat idea that is really more of a feature on an existing product.
It would also allow for more conversation since the readers would not have to comb through as many applicants.
