If you are in Chicago you must check out this new implementation of Microsoft Tag, we saw in the Chicago Tribune today. There is a new walking tour of historical buildings in Chicago that allow users to use Tag to download more information about the site they are at, complete with a map information about ten early Chicago skyscrapers.

The Chicago-based Society for Architectural Historians expects the Microsoft Tag tour to be up and running this weekend in time for its annual convention in Chicago from April 21 - 25.
