Doing an SEO experiment:
Click the Link, then click the +1 and FB on the top right of the page.
Well, I did and the G+1 wanted me to log into Google (I did not as I don’t want it on this system) and the other one like FB
said there was an error when hovered over, but, when clicked, it added the +1 to the count. Hmmm…
I’m not sure why you would see an error, but I did hide the CSS that drops down a pop up menu to comment. These are URL likes, rather then a fan page like, supposedly google uses these as social signals to boost rank in the search results.
I just went back to it and there is no error when I hover over it now…
