Dopplr

I started using Dopplr recently. I never would have considered using Dopplr, except that a few of my friends travel about as much as I do, and I am constantly trying to figure out how to catch up with them.

The biggest bonus is that Dopplr integrates well with Facebook. I only have four friends on it right now, but I am pretty sure that as friends join either Dopplr or Facebook it will act as a natural crossover.

I am beginning to think that online Social Networks are critical for roadwarriors in a Globally Integrated Enterprise. [.PDF] It is pretty much the only way you can have a life outside of work if you spend a lot of time away from home.
