I use it almost everyday and for multiple states....a bit obsessed about where I'm hunting next. I've found that the latest photo's date varies greatly by location and zoom level; ie: the latest photo of Spirit Lake might be from 2011 but move over 25 miles towards Mt Adams and you might be looking at 2010. As I zoom in to look at my own house I at first get a 2010 picture, but if I really want a closeup I am sent back to 2008. Apparently the last time a usable hi-res photo was taken of my area. Imagine the luck involved in finding enough clear days to get good photos in Western Washington.
As was mentioned in a prior reply, the timeline feature on the bottom left can be used to find a better picture, but sometimes all of them are disappointing. I don't know why they'd use November photos of the mountainous areas, but they sometimes do.
The way I see it is: IT'S FREE! and one of the coolest most useful tools ever, so I have no complaints. You can upgrade to a "PRO" subscription for hundreds of $$$ but I have no idea what that gets you.
