I've added Google +1 Button on my WordPress.org blog. Several plugins are already available to help you add Google +1 Button to your posts.
is the google +1 effect anything on ranking or pr? I am not sure is google using data from it. but i am going to put it on my blog too.
I put it on one of my sites few days ago with a simple-to-use Wordpress plugin. We'll see what happens.
Yeah I have added it, but you know what.. as much as they say it will help with your rankings, I can't help feel it's a great marketing ploy by Google to get millions of bloggers to add a + 1 button next to those facebook like buttons as they try to get a foothold in the social market.. We all know how much they hate it that facebook and twitter stand head and shoulders above them in the social area.
