A site co-founder here. Great idea, this is much more of a continuum from vision to execution (sort of like extrovert vs. introvert) than a binary issue. I agree. We'll consider a new type of input option for many questions that are structured like this. Also, it's certainly worth mentioning that we are taking a risk by trying to match opposites to allow for many different skillsets in a team. Although Dr. Wasserman's research right now supports this variety in founding teams I think much more research needs to be done along these lines. We hope to help collect some of this data over time to be more confident in our approach through feedback from users on the site. Thanks for taking a look at the site and helping with your comments. More updates to the system coming soon. - Aaron
