Microsoft employee and MSDN blogger Jason Sack is very impressed with Google Earth, But thinks he can do better (good, I too love competition). He also wonders if the application will ever be more than a niche product.

Yes of course it will. It will completely revolutionize how we mentally place information. Via Jason Sack’s comments, Dean Heckler provides an eloquent response:

A quick look at its file format reveals its simple to create your own content – the same feeling I got when I looked at HTML for the first time in 1995. This leads me to profess that Google Earth is not a niche application, but the first truly engaging Earth Browser.
