Apparently there are quite some people that never saw Nikhil Kotari's Virtual Places sample application.

This is a quote from the website:

The idea behind Virtual Places is to highlight Virtual Earth in a mashup-style (aka Web 2.0 aka Programmable Web) application, wherein other Web services brought into the application in the form of gadgets (ala live.com). The application is implemented using ASP.NET Atlas, and features a complete mapping framework built using Virtual Earth and Atlas that features a programmable map control, overlays and pushpins.

This web application uses different services, such as the Amazon E-Commerce Web services, Amazon Alexa service, Weather.com, Flickr, GeoBloggers, MSN Search Web Services, FeedMap and GeoURL. As stated above, it was built using ASP.NET "Atlas".

Speaking of this package, a new version was released a few weeks ago. If you want to try out "Atlas" for yourself, you should be using Visual Studio 2005 or Visual Web Developer Express (this last one is available as download from Microsoft).
