Author Monica Valentinelli shares
an essay about the value of social media and how its presence and absence affects her writing. I have discovered pretty much the same things whenever I've taken a break from LJ/FB/Twit/etc, and I bet I'm not the only one. Unless you're seriously addicted, I don't think you need to go cold-turkey as Valentinelli did - a day or two off, and you'll discover whether you're addicted or not.
Speaking of which, off goes teh interwebs! I'm off to wrap up some work stuff and then get some of my own work done. I won't be gone for months, though - more like hours ;-)
