There are already some tutorials out. Here's one:[howto.cnet.com ].
Give it a few days, there'll be more tutorials, and the inevitable videos on the tube sites (if they aren't there already).
Seems like too good an opportunity for a brand to pass up, especially since Google+ seems reluctant to release this feature.
