I think you totally missed the point: geography generated higher clicks on this ad because people were overwhelmingly more interested in the location of a job than what it was for. Because Diabetes AutoMeters Inc™ that Raganwald thinks should get the engineering energy isn't located in the valley, it won't attract engineers from the valley. Similarly, because so many ad-driven companies are in the valley, many of the engineers that want to be (or already are) in the valley tend to end up working on advertising stuff.
