Of all the American internet industry’s critical events (other than that fateful night in Mark Zuckerberg’s dorm room), odds are good that Williams was there or knew someone present.
That's why in my opinion. He probably has the best network in the valley.
I was surprised recently that my wife knows who Ev Williams is (she's not technical at all, doesn't blog, and doesn't tweet). Surprised because he's not Gates/Jobs/Zuckerberg famous. Yet, I guess it makes sense because being responsible for blogging and Twitter is a pretty big footprint of influence even if he's a lot more low-profile and non-aggrandizing than those other guys.
Compared to most Silicon Valley founders he was, his adoptive parents were blue collar with no college education. His dad made most of his money as a repo man.
Part of the agreement his biological mother made with the Jobs family to allow them to adopt was that Steve had to go to college.
That's why in my opinion. He probably has the best network in the valley.
