The Concept of Pull with HackerSpaces

I imagined that the concept of Pull as described by David Siegel would be a boon to Hackerspaces. I would guess that each person would be found by others without the need of a large marketing budget. They could sell their product, partner on projects, and receive funding all because someone else found a need ... and in a utopia, the web of linked data would make this possible. At least, that is how I see it.
