Google has announced that the free domestic calling using their Gmail service will continue to be free throughout all of 2013. A nice Christmas and New Year’s gift for those who currently utilize this service. I’ve used the video chat feature in Gmail a little bit, and while this tech (video calling in general) is still in its infancy, I believe its truly the way of future. And as more and more folks get mobile broadband services, this type of free service will impact a greater number of folks. Good times!
