Merlin Mann's "43 Folders" blog is devoted to turning the advice in David Allen's amazing productivity book Getting Things Done into material that is suited to people who lead technological lifestyles (Getting Things Done barely mentions computers and doesn't have anything on stuff like hacking producivity with perl scripts).
But sometimes Merlin goes low-tech, as he did with his amazing post from last September on the "Hipster PDA" — a bunch of index cards held together with a binder clip. Now he's extending the Hipster PDA with tips and tricks he's derived since then. It's great stuff — Craig of Craigslist carries around old business cards in his shirt-pocket with notes to himself in tiny writing on the back of them. Hipster PDA is like that on steroids.
The Hipster PDA (Parietal Disgorgement Aid) is a fully extensible system for coordinating incoming and outgoing data for any aspect of your life and work. It scales brilliantly, degrades gracefully, supports optional categories and “beaming,” and is configurable to an unlimited number of options. Best of all, the Hipster PDA fits into your hip pocket and costs practically nothing to purchase and maintain. Let’s make one together.
