This guy is impressive.  He unplugged from all social networks, from all email, and from his phone, and went old-school.

If I didn’t think I would immediately get the shakes, and if I didn’t need my phone/email for work (and if my mother wouldn’t freak out because she wouldn’t know if I was going about my daily routines or “lying dead in a ditch somewhere”), this would be an epic challenge.  Although, paradoxically, I would want to blog about it as I went.  Damn you, technology!
