80% of Mobile Calls Go to Just 4 People

"Although mobile phones make it easier to keep in regular touch, a typical user spends 80 percent of his or her time communicating with just four other people," says Stefana Broadbent, an anthropologist with the User Adoption Lab at Swisscom. Think of it as the long tail of communications.

Broadbent also says different channels get used for distinct reasons. Mobile calls are for last-minute coordination. Texting is for “intimacy, emotions and efficiency.” E-mail is to exchange pictures, documents and music. IM and VoIP calls are “continuous channels”, open in the background while people do other things.

Also, you won't be surprised by this finding, but texting is on the increase. “Users are showing a growing preference for semi-synchronous writing over synchronous voice,” says Broadbent.

And though enterprise IT managers might not like the idea, private communications are invading the workplace. Workers expect to be plugged into their social networks while at work, whether by email, IM or mobile phone.
