Interesting concept, I always believed this approach to Intel was inevitable. Open source intelligence already plays an important role in the current IC structure.

I believe some Intel communities actually have controlled and dedicated applications (similar to wiki and socials) for collaborating on intel.

I am very curious to see how this would function once implemented.

One thing I think is important to consider in the early stages of developing a system like this is taking efforts to stress good intelligence practices.

Integrating a rating system may be beneficial. Ratings on importance, relevance and accuracy.
