As focus fusion is somewhat of an open science project, this might be a good place for interested people living in and around Chicago to turn to.

We can learn from their approach, starting with a clean looking page that qualifies people by sub-interest. This ties in with what Emmetb posted about building the FF brand and using AdSense for monetization. But since Chicago’s only about a 5 hr drive from here in West Michigan, I’m kind of wondering about how global their thinking is at the moment.
