As you visit the refreshed Zune.net you will notice the International link above the zune logo. As of now it only displays Canada but pretty soon I'm sure Zune will start expanding outside North America.
The new site seems jam-packed with links and information. The Zune social has changed a bit, it now displays "About Me" information and a Friends Activity collage of recently played tracks in flash. Looks cool.
As of writing, I still cannot connect and login to Zune Social using the Zune software, but I can login on the browser. It's saying something about firewall but I think the problem is on the server-side.
