Wolfram Alpha that I like is the "fact sheets" that are available for most topics. For example, if I search for something like Ted Williams I will receive a list of key details about his life. Then if I want to I can print or download that fact sheet.
Alpha Maps is a mash-up of Wolfram Alpha's fact sheets and Google Maps. On Alpha Maps you can enter the name of place and see it on the map with all of Wolfram Alpha's associated fact sheets for that place.
Applications for Education
Alpha Maps could be good tool for students to do some quick, basic research about places that they're studying in a geography lesson. Unlike an atlas or almanac that might have just a map or just a list of facts on one page, on Alpha Maps students see the information about a place layered on top of the places they're learning about.
