If you want to see how the majority of people will behave in the future then look at how teenagers are behaving today. That's the message Facebook's chief operating officer Sheryl Sandberg put across during her presentation at the Nielsen Consumer 360 Conference in Las Vegas.

And what teenagers are certainly not doing is emailing according to the figures Sandberg produced:

“I hate to be the bearer of bad news", she said. "But in consumer technology, if you want to know what people like us will do tomorrow, you look at what teenagers are doing today. And the latest figures say that only 11 per cent of teenagers e-mail daily. So e-mail, I can’t imagine life without it, is probably going away".

Sandberg stated that teenagers are more likely to send an SMS or, less surprisingly since Sandberg works for the biggest social network in the world, they are likely to use the messaging services within their social networking service.

The 11 per cent figure was based on a report by the Pew Internet & American Life Project that also found 54 per cent of teenagers texted on a daily basis, 38 per cent made or received voice calls on their mobiles and 30 per cent of teens talked to each other on a landline phone every day. Only 25 per cent used social networking sites every day to communicate with their friends but Sandberg expects this figure to grow.
