Dallas News blogger Andrew Smith picked up on the TeleGeorgraphy survey showing howSkype now leads the world in cross-border voice calls.

He provides some analysis on Skype:

"Skype has really improved audio quality over the past couple years. When I first started using it, people asked me if I was using a tin can rather than a telephone. That doesn't happen anymore, particularly since the release of version 4.0. The sound is good on all calls and the sound on a Skype-to-Skype call is great -- far better than on a traditional landline telephone.

"And all the other features -- video, call recording, screen sharing, etc. -- blow standard phones away."
