Dopplr is an interesting service. In short, it’s a way to share your travel schedule with others and possibly “hook up” with people when you’re someplace.
While I’m not sure where the monetization opportunities are for this service, they did receive some funding recently. Good for them. I hope they develop this idea further, but do me a favor: keep it simple.
This video gives a good description of the Dopplr functionality.
