The tech is easy but building the content and getting people to participate is the lynch pin. Vertical Scope isn't interested in any particular niche. They are interested in the portfolio and being able to mine the existing content via search engines. As the other post indicates they'll never sell the content.
I'll send an email to Jeff. I believe he was trying to get this done for you guys.
