No, we're not talking about Facebook's IPO fiasco earlier this year and the subsequent stock price meltdown. It's bigger than that.
Facebook is worst offender among the many Internet distractions keeping workers from getting things done in the office.
Most workers stop what they are doing several times an hour to respond to messages from friends and co-workers on social media like Facebook and Twitter, browse the Internet, and check and respond to e-mail.
And once distracted, it takes time for a worker to get back to the task at hand - one study put the average disruption at 23 minutes.
All those interruptions add up to a massive expense for businesses and the U.S. economy.
