A fun game to play while working from a cafe with WiFi: Check out the shared music playlists in iTunes, then try to figure out on the basis of the collections which playlists belong to which of your laptop comrades.
Also, two free business ideas for those cafes:
- Hook your speakers to an Airport base station and create an ever changing jukebox by letting people stream stuff from the collections on their laptops. Of course, you might need to come up with some sort of application to mediate this so you didn’t have people hijacking the soundtrack indefinitely.
- Put a clickable map on your website of the seating layout of the cafe. That way, in bigger places where it can be tough to catch a server’s eye (cough, Tryst, cough) you can signal to the front counter that you’re looking to order something.
