Using Sphere for Sharing Related Content

I added the Sphere widget to my site today.  You'll see a little icon right at the bottom of each article.  Do take a look.  It is context sensitive so you might get different results if you client on an article then click the sphere button versus clicking on the sphere button from any article on the home page.

My initial tests show that the related content links provided are quite relevant which is impressive.
