The Facebook of the travel community, this is one of the few travel networking sites that has a really mainstream following (membership is currently over 13 million). Where Are You Now? lets you keep track of friends, family and on-the-road buddies based around either where you are, where you've been or where you're going. Understandably popular with gap-year travellers when it started out, it's now gone global.
