Nine years ago, I called on Mark Zuckerberg to resign as Facebook’s CEO, after a string of internal and external missteps that, as I wrote in Valleywag, “would have led to any normal CEO’s firing.”Perhaps my timing was off, given the 1.8 billion users and the $450 billion in value Facebook has accrued under Zuckerberg’s leadership since then. Fine: Call me an early adopter.
