Merlin Mann of 43Folders is a smart guy when it comes to managing all the facets of your "digital life". Here is a presentation he gave recently at the IDEO offices. The 43Folders name comes from David Allen's Getting Things Done methodology, so if you're a following of that way of thinking, then you'll be right at home with Merlin. But even if you're not, Merlin is still worth paying attention to.
