It might not be a big thing to you, but when I want to look at what my yard looked like five years ago, I go to Bing Maps. I didn't think about it until last year when my sister told my brother that she saw his new fire pit on Google Maps. I wondered if mine was there, too. It sure was!! But the Bing Map shows a pretty primitive area out here...

Maybe they are both always updating different parts of their mapping, I don't know. But just that aspect makes Google look a lot more on the ball than Bing.

Sorry about late replies around here, I don't get to read often...
