Whether you’re a city hopper or a slow traveler, the newish website Dopplr.com, founded in 2007, may be an interesting social networking tool to add alongside your Facebook, MySpace, or LinkedIn accounts.

The idea of Dopplr is simple. By creating a free account and noting your upcoming travel plans, you can let friends, family, and acquaintances keep you on their radar. If they also create an account and indicate their travel plans, then Dopplr will automatically let you know whether your paths might cross. Dopplr makes calling ahead and making arrangements to get together seem downright antiquated.

Clean of ads and functional, Dopplr has gained favorable coverage from TIME, The Wall Street Journal, and The Guardian.
