For what it’s worth, I’ve always thought that blogging, not Twittering, was the media version of crack. Metaphorically speaking: I get an intense high from instantly publishing, but the minute I stop, I get a kind of an empty and anxious feeling, as if I’ve just poured part of my soul into a spiritual void. I stopped smoking crack ten years ago–it got a little out of hand– but I have come to terms with blogging. It’s healthy as long as I don’t allow it to totally consume me.
