Get a pulse for the posts your readers like most with the +1 counter:
As we mentioned in our Connect to Google+ post a few weeks ago, we’ve been hard at work to bring you new ways to grow your blog and engage with your readers using Google+.
Today we’re happy to introduce the +1 counter, which allows you to quickly scan your dashboard to see which posts are most popular on your blog. Each time a reader clicks the +1 button on a post, a +1 gets added to that post's counter and their profile photo and name will appear.
