43 Folders is “Merlin Mann’s site about personal productivity, life hacks, and simple ways to make your life a little better.” And I am thouroughly enjoying his advice, viewpoint and take on “getting things done.” In fact, he has some excellent GTD resources. Please see http://www.43folders.com/2004/09/08/getting-started-with-getting-things-done/ for more.
He also podcasts and recently got married!
