MICROSOFT BUYS INTERNET STARTUP YAMMER FOR $1.2 BILLION /AP- “Microsoft is paying $1.2 billion to buy Yammer, an Internet startup that has built a social network similar to Facebook for the business world. The deal announced Monday comes nearly two weeks after word of Microsoft's negotiations with Yammer leaked out in published reports.
