For my example of a Web 2.0 product I chose Google Earth. The reason for this is the revolutionary way that Google has created a brand-new platform for collaboration, community and information gathering.
At first glance Google Earth seems to be just a 3-D mapping application; however, if you explore the additional functionality, you are introduced to a multitude of tie-ins. These are a sample:
- Layers: Using Google Earth Layers, a user can overlay information from a myriad of sources. Powered by Google search and other feeds we now have graphical drill-down access to information ranging from restaurant locations (think Ad Sense revenue!), community services, transportation, shopping to even historical volcano and earthquake locations.
- Wikipedia: Building on layers, the information provided by the Wikipedia community adds deeper-levels of knowledge to Google Earth, readily enhancing the quality of the service.
- Google Earth Community: A good deal of the application’s development no longer rests solely on Google. By leveraging a community model, individuals from around the world including GIS mappers, photographers and hobbyists are all capable of adding unlimited content (new layers, pictures and information) in a self-policing, on-demand manner.
Nothing.
Encyclopedia Britannica, Encarta, Yahoo, Mapquest, et al are woefully unprepared.
