Dopplr Updates: More Cities, Facebook App and Unlimited Invites

Dopplr, a social network for travelers who recently picked up a round of VC funding, has announced several updates to the Dopplr service. First up are more cities to use Dopplr in which will allow more people to find uses with the tool.

Next up is a Facebook app called "Where Next?" which also offers friend functionality so you can see who else in your Facebook clan is using Dopplr.

Lastly, while Dopplr is still in a closed beta, they have created unlimited invites for those already in the system. So leave a comment if you want an invite!

I have enjoyed using Dopplr so far and many of my European friends and associates are using it as well.
