Dopplr went live while I was traveling last week, and I’m just now getting around to noting the fact.

Dopplr does something simple: It tells you which of your friends are going to be in the places you’re going to. And it does it quite simply, even though specifying places is actually quite a daunting task: Did you mean Paris in France, Texas or the other dozens of places on earth that share that name? The Dopplr UI makes entering this info just about as painless as possible.

Or course, my good feelings about Dopplr, where I was a beta user, are abetted by the fact that the people doing Dopplr are among the people I like and respect the most on the Web.

BTW, here’s a moderately funny video parody of Dopplr from Mahalo.
