Dopplr is an online service for frequent business travelers. Dopplr lets you share your travel plans privately with a group of friends and colleagues whom you have chosen. It then tells you when people you know will be in the same cities. It also reminds you of people who live in the places you're planning to visit. Dopplr works on your personal computer and mobile phone. It links with online calendars and social networks.
