When two of the publications we most trust mention a new travel website, we’re all ears. And when the site is as bright and as blogged about as Dopplr, it becomes a forceful blip on our radar. The newly launched service allows business travelers to monitor contacts’ trips so they can meet up if crossing paths in airports, cities, and countries, sometimes with only minutes to spare. If you like the idea of taking fate—and possibly your career—into your own hands, sign up to start greeting friends and colleagues on the fly. A couple of added bonuses: airport food tastes better at a table for two, and a night out in a new city is more fun with a partner in crime.
