Does Google drive a significant amount of organic traffic to Stack Overflow for short term searches? I permanently disabled Instant after a few searches, so I have no opinion one way or another as to the effects of it on search. However, it seemed like it was designed to be useful for short queries. Stack Overflow, on the other hand, is extremely useful for long tail searches. To be honest, since I typically use SO to solve a specific problem, I don't know what short terms I'd use to land on a page of interest.
