"I’m curious to hear how it’s going for you"

Well, I use Outlook to get things done, and I can't imagine ever being able to reduce myself to a list-based system without the interlinkage, automation, and aggregation Outlook provides. (Perhaps this demonstrates that I am still too much engrossed with the 'tweaking'!). I did download GTD TiddlyWiki to have a fiddle, and have ended up finding it immensely useful for collecting all those small pieces of information that escape classification or do not require a whole piece of documentation (like the list of who has what type of coffee when we order the real stuff, and how to change the date format back to Australian dd/mm/yy on a freshly-formatted computer). Previously I created word documents for this type of information, sometimes trying to group a few small things in one, and used to dread having to find them.

I guess this is not response about GTD, as I ended using the GTDTiddlyWiki more like a vanilla TiddlyWiki, but I am glad to share how immensely useful it has been, taking the stress out of common but irregular tasks, and providing an excellent secondary location for reference materials.
