Matt Cohler has a unique perspective on Facebook — the venture capitalist, a partner at Benchmark Capital, was not only vice president of product management for the company until June 2008, he was also a founding member of LinkedIn , and now he's an adviser to Zuckerberg.
He told me he doesn't focus too much on stocks near term fluctuations — and neither does Zuckerberg. He shifted focus to the company's growth, saying "the fundamentals of the company are really strong."
With mobile growth proving Facebook's biggest challenge, Cohler told me that Facebook's mobile opportunity is "enormous," saying it represents "the spiritual core of Facebook." He's optimistic about mobile and the big picture, saying people "have always underestimated" the company. (Read More: Facebook vs. Twitter, Who Has Edge in Mobile Ad Wars?)
