The success of StackOverflow was built on the backs of smart programmers who don't say anything unless they have something good to say. I've been to a few of the other StackExchange sites and the communities were not the same. Mostly the blind leading the blind.

StackExchange 2.0 is a weak attempt at still trying to replicate the unreplicateable (I know this is probably not a word). It will fail because few of these "new" sites will not pass muster during the beta phase.

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.
