Google Talk

I had known about the today's release, but I didn't know that many of my contacts would invite me to Google Talk. Looks nice, I have a few people now on my list now but it isn't possible to call or chat with non-Gmail users through Google Talk. But you always can send a Gmail invite to a friend. The system of voice transmission is very good, maybe better than Skype's. To know more about it read Google Blog. And go test it.
