Going back to the reputable investment mechanism, I think this is needed not only for investors, but also for startups. No startup company wants to deal with thousands of different ownership voices - its better to have a concentrated voice (e.g. VC fund manager) raising only the largest issues. Rather than encouraging individuals to invest (like Kickstarter), give all individuals the ability to invest in funds created to invest in specific startups (e.g. Turntable fund, Pinterest fund).
