1) I'm not relevant.
2) I don't want to understand the most popular site on the internet, which my publication writes about regularly.
3) Despite my position at a publication that relies on technology and social media as both a promotion tool and main subject, I want to annoy my PR contacts and writers by forcing them to use other techniques to contact me.
4) It's the hip thing to do for the ahead-of-the-ahead-of-the-curve trendsetting techies like Jason Calacanis and I want to show that I have something in common with that guy.
5) I use privacy as a crutch to shield my real reason for not using Facebook (below).
6) I want to be contrarian for the sake of being contrarian. And as a side effect of that, I'm choosing to no longer be relevant in my field of technology.

I do not understand how someone in his position can do his job and recuse himself of Facebook. You don't have privacy: You're the editor of a major publication that covers technology.
Got a problem with that? Don't overshare. Make a fan page so people can worship at your altar, and turn on your privacy settings so nobody else can see your data. Use your head.
But you edit the U.K. edition of Wired, one of the most popular technology publications in the world. And you don't use Facebook. It's like wearing a giant sign around the office that says "I don't deserve my job."
