Facebook’s Fluctuating Fate

Daniel Gross discounts anything the company tells investors:

In the digital media world, projections about what will happen three years from now, let alone one year from now, almost always defy expectations.  … In 2008, could Zuckerberg have projected how Facebook's users would grow by 2012? In 2009, would Facebook have told shareholders that it would consider spending $1 billion on Instagram? No. Instagram didn't exist. Business models come and go with such speed that anything a CEO — even one as legendary and awesome as Mark Zuckerberg — tells you about the near-term future is likely to be wrong.
