Most people would guess that teenagers send more instant or text messages than emails. In the U.K., says ComScore, it is a quantifiable trend. As it turns out, people now are communicating more from within the context of their social networks than using portal-based email. That isn't yet true for business communications, of course. But it stands to reason that personal use of email is for communication with friends and family. And if those people are part of a social network, one doesn't have to go outside the network to send messages. Some day soon, people will launch and receive voice, video and other communications from within the social network as well.
