The Guardian US interactive team has posted, “A Guardian guide to your metadata“; and for anyone who is still bewitched, bothered and bewildered by the concept, I urge them to take a look at this interactive demonstration.

What’s also interesting is that one of the examples they use is the Petraeus scandal, just like I did a few months ago.  The reason it’s such an excellent learning tool is that individuals tend to worry about their own metadata, completely ignoring their risk of harm by others’ metadata.

Obviously, with the strange happenings at the NSA, this might be the perfect time to understand the world around us a little bit better.
