Ok, I’ll admit this is more than a little nerdy, but I finally got around to using Wolfram|Alpha’s “facebook report” option. That’s not especially nerdy, I suppose, but my fascination with the analysis tools provided certainly is! Here’s the basic method for exploring it for yourself from a post at lifehacker. (Note: I altered the approval so that only I can view any posts from the Facebook app. This insures some privacy protection and that I won’t be filling friends’ news feeds with unintentional posts.)
All you need to do is head to Wolfram Alpha’s home page and type in “Facebook Report”. After connecting it to your Facebook and granting it a rather large number of permissions, Wolfram Alpha will break down everything about your Facebook activity into 60 different sections of charts, graphs, and other analyses—like a cluster map of your friends and relationships, everywhere you’ve checked in, what days you’re most active on the site, a cloud of your most-used words, and even the weather from the day you were born. It’s incredibly interesting, super geeky, and downright scary.
