You know Facebook's got dirt on you, it's one of modern life's unavoidable trade offs. Now though, thanks to Wolfram Alpha, you can data-mine yourself -- something its creator has been doing for years -- and get a true sense of exactly what the social network knows about you. You'll first have to head over to the computational knowledge engine, then search "Facebook report." Follow the prompts to give the app permission etc, and you'll be rewarded with a detailed breakdown. The data shows information about your interactions, friends, most popular photos, most common demographics and more. For example, you might discover that you know someone in the Philippines, have a clutch of non-connected friends weirdly in the same location, or that you mom is your top post commenter. Though you probably knew that last part already. Paranoid or curious? Jump on the source link to get started.
