I find it interesting that people are finding issue with the $12K. Personally I have kids and mortgage and I will be applying with my healthcare startup which as it happens is in very early stages.
I would have applied even if there was no $12K since, YC is not taking any equity in this case, and, is providing access to its network which is worth much much more than $12K to me.
>access to its network which is worth much much more than $12K
Very true. But do not forget that this time there would be aspiring candidates from outside USA too. For them $12K would be a huge enabler (Ex.: adjusted for purchasing power $12K = ~$75K, for somebody who is in India).
