This graphic is from an InsideFacebook article about Facebook Connect, but for me the picture spoke more than the article.  It was a visual punctuation of the ubiquity of Facebook.  It goes with us on our mobile phones, it's our companion on our gaming consoles, it's a stand alone application on our desktops, and it's there for us on the web like a trusted friend as it has been from the start.  It will be exciting to watch the socialsphere as more and more seemingly non-related entities integrate aspects of social media.
