Microsoft to buy Yammer for $1.2 billion
Microsoft announced on Monday that it would buy Yammer, a social network service for businesses, for $1.2 billion in cash, as it seeks to strengthen its enterprise software business and compete more directly with Salesforce.com.
``To this day, I would say the best thing for Microsoft is to buy Yahoo,'' Yang said yesterday, during an on-stage chat with journalist John Battelle at a Web 2.0 summit on Internet Age companies and their business strategies.
