Wolfram Alpha Personal Analytics for Facebook

Wolfram Alpha has just released a very cool analytics tool for looking at your Facebook network.   The tool will tell you all sorts of useless information.  For example: The oldest and youngest friends; your posting history by time of day, day of month...; Geographical make up of your friends; how many are single; your exact age to the second... and so on.

It is easy to do.  Go to the site and enter "facebook report" in the search field.
