This could be really useful, but it feels like the bootstrapping phase might be difficult to get past -- on one hand you need to reach the size and level of repute for companies be willing to deal with the process, and on the other you need to provide a sufficient value proposition for candidates to contribute to the guild. I also have some concerns about how you manage problems as this sort of guild scales. How do you keep a consistent standard of skill? what if members performance changes over time?
