I think they do look at different industries on a case by case basis, as Matt says. In a lot of the previous updates, people would say their niche has been affected so much, but I noticed nothing in mine.
Then, suddenly this time, the SERPs were all over the place. Up, down, and all around. Last week we had an across-the-board ranking drop (1-3 spots, generally) for some keywords and then this week it was almost completely reversed.
