DOPPLR
— Once in a while, you find a web application that, beyond having a bit of a ‘cool factor’, it is also useful. This is what it takes for any product to be successful and DOOPLR has this potential.
I am actually a bit jealous because I had about the exact same idea (I am not trying to brag… congratulations to the DOOPLR team). See, I am lucky to know many people around the world. We communicate through an online group where every so often, somebody from the group travels e.g., to San Francisco and wants to see if anybody happens to be in the area around that time (this actually really just happened a few days ago). Now there are about 150 people in that group and keeping up with everybody’s address and travel plans seems almost impossible… DOOPLR to the rescue:
How does Dopplr work? It lets you share your future travel plans with a group of trusted fellow travellers whom you have chosen. It also reminds you of friends and colleagues who live in the cities you’re planning to visit. You can use the service with your personal computer and mobile phone (source).
As of now, DOOPLR is per invitation only. I am hoping to grab one of those invitations at the where 2.0 conference. In that case, I will report back.
