Does Silicon Valley Have an Insider Trading Problem?

The author should mention that to trade on these alternative markets one must be an accredited investor (ie have a net worth of $1 million or earn $200k per year). He kind of makes it sound like any employee with equity could take advantage of privileged information.

But that's not the case, and if I wanted to buy into these companies, for any reason, I couldn't because I'm not sufficiently wealthy enough. That's too bad, because I'm certainly much more educated about this world than I am the general public market.
