Here’s Starbucks’ caffeinated take on social networking–a site within a site that allows customers and partners (aka Starbucks’ employees) to share, comment on and rank new ideas, with the most favored ideas rising like frothy cappuccino foam to the top. Most importantly, the site has an “Ideas in Action” section, where the best ideas and most frequently raised issues are discussed. If they keep this site alive, it could grow into a real dialogue between the company and its customers. At the very least, it gives Starbucks a good sense for what flavor of frappucino their die-hard latté junkies are jonesing for.
