Goog!

I found out about Google's "My Maps" from a blog linked from lolcode. You can overlay maps with placeholders and shapes, and as far as I can tell it even remembers the way you have the map positioned when you send a link around. We were testing some 400 MHz radio modems the other day so I gave it a try. All it's missing is a way to measure line-of-sight distance without using a ruler.
