On the whole, I find the new GA to be very clunky and a lot harder to navigate than the previous version.
Now that they are adding new features like this, it might be time to start getting used to it.
Clunky? That's the opposite of how I see it. It's much more stripped down; the nav menu is far simpler and less bloated.
It's not yet showing as a feature in my analytics, but I look forward to testing it out.
First, you have to be logged into the "new" Google Analytics. Second, it shows +1 tracking by default. To use it for Facebook and Twitter, you will have to modify your GA script. More here: http://code.google.com/apis/analytics/docs/tracking/gaTracki...
Can't wait to see people integrate things like the Reddit's upvote buttons or Stumble's thumbs up into Analytics.
I didn't have it either. You may have to go up to the top and click "New Version" in all red.
