Google +1 buttons on AdSense ads soon

Google is planning to introduce +1 button and personal recommendations to display ads. They plan to roll out this new feature from October 1st.

Extract from blog post +1: Now making Display ads more relevant on Inside AdSense Blog:

Starting in October, the +1 button will begin to appear on display ads on your site. With a single click, people will now be able to endorse specific ads and make them more likely to appear to their social connections.  We believe that these recommendations could lead your readers to notice ads on your site more, leading to more clicks and higher returns for you over time. 

Google hopes to deliver more relevant ads based on recommendations from your friends and connections. It will be interesting to see this in action.
