Gowanus would be cool, except it's a bit far out of Manhattan, which is why DUMBO works.<p>DUMBO is a desert in terms of food choices though. (Not that South Park is any better), but DUMBO is also expensive to live in. I say put all the startups in Greenpoint (cheap labor (hipsters), low rent, and mccarren park!).<p>On a more serious note, I think it would be nice to have a dense concentration of startups in a nice part of town but I don't know how one would pull that off.
