Huh? They built StackOverflow too. From zero. Are you saying there aren't other communities of with good S/N ratios, or that SX2.0 won't be able to find them?

I forgot to add the word "community".

It should read: "The success of the StackOverflow community was built on the backs of smart programmers...

And yes, SX2.0 will have a hard time building the critical mass around anything other than programming.
