Figure 1. "Wolfram|Alpha, the world's first and only computational knowledge engine, uses its expert-level knowledge and algorithms to answer questions, generate reports, and do analysis across thousands of domains. And the newest domain is your own life and social network, as seen through your Facebook!"

They roughly divide into 3-4 categories which I have to say is pretty accurate.
You can generate views that show you your male or female friends, those younger or older than you, and from your home town or the place where you live.
That big blue blob on the left side are connections made through or via social networks like Second Life, Facebook, Twitter or Empire Avenue, most of which I have yet to meet in person. What remains are colleagues, friends and family. It's just that easy to meet new people in the digital space these days, and to me this graph is evidence of that.

There are actually quite a few facts being made available in the report, such as the age distribution or who your friends are who have the most friends. Perhaps too much to tell in a single article.
One of the more interesting ones is a section dedicated to telling you whom the "social insiders", "social outsiders", "top social connectors", "social neighbours" and "social gateways" are in your network.
This article can however merely give you an idea of what's in store for you should you decide to run the report. If you do, what stood out most for you?
