The March 16 _Chicago Tribune Red Eye_ ran a story about Foursquare, a new social web site that allows users to post updates on their real-time whereabouts, using mobile devices. Aspects the story discusses included the site's potential to publicize users' favorite local businesses, security and privacy concerns, and the "TMI" phenomenon and how it reduces some people's interest in Foursquare.
