"Check it, this site should be big for 2008, and a great online app for travelling, people. You tell where friends are and where they'll be."

So said one of my always-online friends, an online trend-watcher extraordinaire - who thanks to Doppler, I now know intends to be in Bangkok next month.

Doppler is the application for people who spend their month in at least three different beds, across three different countries. Or for those who know a lot of people like that.

According to the website, "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."

So if you can never keep track of your friend Liz without first talking to her secretary, get her trained up on this.

Praised for simple and elegant design, according to Dopplr, business travellers love the site. Well, they would say that.

Jimmy Wales of Wikipedia recently named Dopplr his "favorite non-wiki website" in The New York Times Sunday Magazine:

"You put in your travel schedule and link to your friends. It allows you to see where everyone is. I love it." The Guardian newspaper has just named Dopplr one of its five "hit websites of 2008."

Out only qualm, here at Media Watch? Those who really travel a lot, usually don't make or take the time to write in sites like this. But then again, maybe they will now.
