Ben Hopper interviewed Reid Hoffman at The Verge.

Reid Hoffman is a Silicon Valley power player. He emerged at PayPal, where he was the first full time employee, but is perhaps better known as the co-founder of LinkedIn. The sale of PayPal and IPO of LinkedIn have made him a multi-billionaire, and he has poured that wealth back into startups as one of the most prolific angel investors in the Valley. More recently he became a full time venture capitalist at Greylock Partners, where he runs the $20 million Discovery Fund, making seed stage investments in young tech companies.

One of the most important things to take away from this is that you should invest in what you know. Reid Hoffman knows tech. He puts his fortune into the future of tech.
