"...stitching errors do occur, and even with no errors you can sometimes spot a significant change in season or ground shadows or, more dramatically, a construction project at groundbreaking on one side of a seam and completed on the other side."
Indeed. I have seen this quite a few times myself. See the attached screenshot of the patchwork that is Elephant Island in Google Earth. Also, sometimes the images you see will change depending on the level of zoom. See the two screenshots of Nonouti atoll. In one, there is a conspicuous band of clouds running right through the middle of the atoll. In the other, the band is barely visible.
