Social networks will become the main form of businesses communication for many employees, according to Gartner...
Some 20% of staff will use social media as their main form of communication by 2014, said the analyst.
"Today, social paradigms are converging with e-mail, instant messaging and presence, creating new collaboration styles," said Monica Basso, research vice president at Gartner.
"The rigid distinction between e-mail and social networks will erode. E-mail will take on many social attributes, such as contact brokering, while social networks will develop richer e-mail capabilities."
By 2012, Blackberry-maker RIM and Microsoft will own 80% of the enterprise wireless e-mail software market, predicted Gartner.
Microsoft and IBM will add links to internal and external social networks from within e-mail clients and servers, making services such as contacts, calendars and tasks shareable across e-mail and social networks, it said.
