Kevin Johnson, the former boss of Microsoft's former Platform and Services Division, had to have thought he'd be moving to Sunnyvale this fall under different circumstances. Instead of riding into Yahoo HQ as a conquering hero, Johnson will take over Juniper Networks, a maker of fine and very boring networking hardware. Conveniently, however, Juniper is just around the corner from Yahoo. One senior Yahoo exec tell us that Johnson should feel welcome to join them for a latte at Beantrees: "Juniper Networks HQ is located 2 blocks from Yahoo’s HQ in Sunnyvale. So he can eat at our cafeteria!" Above, we've provided a Yahoo Map with walking directions to make the trip that much easier. Welcome to Silicon Valley, Mr. Johnson.
