A loyal reader asks: I am on the road constantly. While I am glad to have the opportunity to go to such amazing international locations, I have to admit that I get a little lonely. Short of sitting with strangers at dinner (which I have been known to do), do you have any suggestions for me to meet people?

Meet people? No, we’re not in that business. But we do have an idea for you.

Dopplr is an online service for intelligent business travelers.

It lets you share your future travel plans privately with friends and colleagues (or those people you hang with on Facebook or LinkedIn or Twitter!). The service then highlights coincidence, for example, telling you that three people you know will be in Paris when you will be there too. You can use Dopplr on your personal computer and mobile phone. It links with online calendars and social networks. Take the tour.

We’ve heard some great things already.

Bon Voyage!
