For example, I liked the Cadwolf idea because the founder has worked as an engineer in the kinds of organizations he wants to sell to. Many of these applications had no info about the founders that I could find. All in all, the vast majority of these apps gave little indication the founders have the necessary background to do their idea.
Just some examples: as far as I could tell, the founding team for Brodlist has no prior experience implementing the internals of database/distributed/operating systems. The Jury Board idea sounds really interesting, but it's an area where I'd like to see the founders have a lot of domain expertise (litigation experience?), and sadly the founder didn't provide any info on that.
Somewhat related, I think it's terrible to vote for Pinboard given the founder's stated dislike of YC (and the founder stating that this is a protest vote). The fellowship should go to founders that sincerely want to make full use of YC's resources for their startup.
