To respond to the general idea of the RFS, not RFS1 specifically: I think this sort of feedback to the startup community is incredibly valuable. I take it as an statement of "what they think the world needs/wants/would-pay-for right now." Having a sense for markets seems a bit like being able to predict the weather based on the way an old injury aches, and young entrepreneurs with a whole lot of energy don't usually have that sense. As one of them, I have to say it's nice to see suggestions of unsaturated/needy markets. It's icing that the advice is coming from someone who also can help bring proposed solutions to market. As a side note, I'd really love if someone similarly informed did this with a philanthropic eye. Think "things the world could really use right about now," since those who feel the pains rarely are the ones with the ability to fix them on a replicable scale. Like a giant to-do list for humanity, maintained by people with a great degree of perspective. But I also have a hankering for a philanthropic equivalent of YC that funds and supports non-loss startups.
