Brain on Blog/Blog on the Brain

I'm hanging out in the office long after everyone else has departed for the weekend, because I am seduced by a broader, faster bandwidth than I have at home. But even here it was something of a Zen exercise to connect to Your Brain on Blog, the podcast that The Atlantic packaged with Andrew Sullivan's "Why I Blog" piece from the November issue. The promo promised two guys -- Sullivan and an Atlantic associate editor who blogs the presidential campaign-- reflecting on "the narcotic appeal of blogging and the occupational hazards of thinking quickly." Made me wonder if bloggers have time to think at all. Where's the line between blogging and babbling?
