A couple of months ago, I briefly mentioned Jeremy Ruston's tiddlywiki. So it's cool to see a GTD-oriented incarnation show up: Nathan Bowers put together a few templates for a Getting-Things-Done system, and made it printable directly to 3x5 cards:
"GTD Tiddlywiki -- all your tasks are belong to you"
