David Temkin, VP-developer platform for Palm (NSDQ: PALM), has left to head mobile for AOL (NYSE: AOL). Temkin will report to Brad Garlinghouse, president of consumer applications, and, like him, will be based in AOL’s Mountain View office. But Garlinghouse’s internal announcement about the new hire stresses a broader role “working very closely with all of the strategy groups to drive our Mobile platform and product experiences globally.”

The memo also echoes the latest battle cry from AOL: “Beat the Internet!”—no details really but Temkin’s mission is “to drive a mobile strategy” that accomplishes that. At Palm,  he was responsible for setting the strategy and shipping the software to support Palm webOS. His resume also includes founder and CTO of software company Laszlo Systems and roles at Excite@Home and Apple (NSDQ: AAPL).
