A few days ago I wrote an article about all the cool things people have been doing with Google Maps. The integration of the mapping services with other services is often called a "mash-up". These mash-up sites offer a lot of great and innovative services and they are made possible by the API's provided by the mapping sites.
Today I found out about the beta projects that Yahoo is working on. One project is a Flash based map which works very much like Google Maps. They don't yet have the Satellite view available, but I'm sure they are working on it. Much like MSN's Virtual Earth, Yahoo's version offers an array of cool new features that are missing from Google Maps. I love Google and all their great innovative technologies, and they are usually the first ones to get the products or services to us, but they always seem to be outdone by their competitors when it comes to features. Maybe they choose not to provide alot of features and keep things simple? No matter what, being able to plot multiple point on a map is very important and I think they definitely need to add that in. Anyway, I digress...
I won't bore you with any more opinions. Why don't you go and check out Yahoo's new map. And when you're done playing with it, see what others have done using Yahoo Map's API.
Oh and if you're interested in creating your own map mash-up, read this interesting article by Dan Theurer: How to build a Maps Mash-up
