Noticed it a few hours ago too. I think this will do wonders for us since it makes our ad more visible! Hope google keeps it! - Although it does look a little messy - but google has always been about results not looks.
Almost every step Google search takes is now to please their shareholders and monetize their traffic (traffic they won because Yahoo had too many distractions). Almost every step Google search takes will result in them losing visitors in the long term.
