My cousin Arty recently turned me on to this website: loopt.com. It's really an application for your phone. It's free to download and works with pretty much every phone (over 100 different models) except, of course, mine - the Blackberry Flip. What's useful to travelers about Loopt is that it turns your phone into a social compass. You can see where your friends are and what they're doing without having to call or text. If you guys 'n' gals are in the same city (or neighborhood), you can connect on the fly, share photos and tips on cool places. You can even share your information with Facebook. Don't worry: Big Brother isn't always watching. You can change your privacy settings at any time if you don't want to be found.
