Holy Ajax! A Browser Based Wiki!
I just stumbled upon this GTDTiddlyWiki. I had no idea these TiddlyWikis even existed. Considering my love of all things wiki I'm shocked. I've been working on using GTD techniques to manage my life and I'll have to give this browser based approach a try. The big feature is that it will output to 3x5 index cards which are my preferred mechanism for keeping lists of actions. It's tempting me to migrate to a hybrid paper and TiddlyWiki based system.
