Last week I received a signed copy of The Start-up of You by Reid Hoffman, the co-founder and chairman of LinkedIn, a site that just hit 150 million users! On its debut today, it hit #1 on Amazon, which is no surprise since Reid has built up an enormous and influential network over years of hard work and dedication. He co-authored the book with another Silicon Valley entrepreneur and blogger, Ben Casnocha.
