On May 25, I questioned and debunked Facebook's "active users" number of 900 million in a column. This month, the company admitted that their unaudited numbers are wrong and misleading. Zuckerberg may be a technological whiz kid, but he has yet to demonstrate that he can run a public company.
I hate to be a killjoy, but Facebook, in economic terms, is a mirage, other than for Zuckerberg and anyone else who has founders' stock. It illustrates the need for salvation, not the road to follow to achieve it.
