The mere fact of who won suggests that you and I were in the minority on this. Most of the problems Dan and Kevin have suffered is due to most people not thinking of what is best for YC.

I agree that we were probably in the minority, but statistically speaking it doesn't immediately follow: Votes for "who do you want YC to give money to" may have been far more concentrated than votes for "who will YC benefit by investing in". I don't know the total number of people who voted; if most people only voted for one or two submissions, then the pinboard-voters would be in the minority.

Only YC knows the answer to this. I would not be surprised to learn that the votes were split into a large pool of people that voted for Pinboard only and another large pool that voted for multiple applications. All I know for sure is they were not voting for mine :)
