VC3 is not for profit - it's a place to discuss questions like these, not the answer to that question. Think of it as similar to a virtual "think-tank."
The community on HN is awesome for getting really nitpicky, but the audience for discussing these sorts of problems is only a small slice of the larger HN audience. I started VC3 as a community formed around a specific purpose (discussing "building meaningful community") specifically to try to build more engaging and valuable discussion, and I personally think that a smaller, closed forum of enthusiastic individuals is a better way to do that than a public general-topic forum.
There's a question in our FAQ [0] that goes into this in even more detail. Look for the header "Why is VC3 its own site?"
