Silicon Valley entrepreneur Peter Thiel is a pretty smart guy. As partial evidence, I give you his self-made net worth of $2.7 billion. He co-founded online payment mega-company PayPal – which was in 2002 sold to eBay for $1.5 billion. Anyone who saw the very good flick “The Social Network” knows Thiel was one of the first outside investors in Facebook. He still owns a chunk, and is on their Board. He invested in LinkedIn. He’s…done well.
