More Interesting Maps
I'd mentioned Amazon's foray into maps earlier, but they've gone even farther and launched http://maps.a9.com with "BlockView Images" for a bunch of cities. It's very Ajax-esque and while I think the dragging of the magnifying glass could use some work (I keep expecting it to work like Google Maps) it's a pretty interesting concept.
UPDATED: This is cool, adding A9 images to Google Maps.
Here's the lay of the land as I see it.
