If you are a constant traveler for either business or pleasure you might find DOPPLR to be helpful as it makes it easy to broadcast your travel plans. DOPPLR, like radar for frequent travelers, finds intersections with your travel itineraries and your friends thus facilitating potential meetups while on the go. I have been using DOPPLR for awhile now and it appears the service has continued to improve. Today DOPPLR rolled out the ability to make your traveling profile public in a release (codenamed "Copenhagen").
The new release of DOPPLR includes profiles, automated trip input via email, SMS and Twitter and more. I really like the simple design of the DOPPLR profile as it offers maps that plot my past and upcoming travels as well as a frequency heat map. Check out my DOPPLR public profile (or in the screen-shot below).
