d3 (d-cubed): Has anyone tried it?
Being a restless soul, I've stopped using a spreadsheet to record my GTD system and I started using dcubed . According to the blurb from the main website page "This system attempts to capture the essence of a "kinkless" GTD system using TiddlyWiki . The most important aspect of this effort is to minimally introduce important "Getting Things Done" features with an interface that is streamlined, intuitive, and clean, without going overboard on "nice to have" plug-ins and experimental features. This application currently assumes that you are familiar with TiddlyWiki..."
Searching this forum I notice that GTDTiddlywiki has been discussed here a few months ago, but not dcubed. I think dcubed is much better than GTDTiddlywiki, while having all the benefits of being a single HTML file, portable, viewable on practically any major browser, customizable etc.
I urge you to experiment with it, especially if your GTD system is computer reliant, like mine. One word of caution. There is a learning curve that you may find steep at first, but believe me, it flattens out fairly fast. There is a Google discussion Group (GTD TiddlyWiki) where I read some useful tips about dcubed.
Finally, but equally important, dcubed is free software.
