Productivity and organization have always been big for me. A couple months ago I got onto a major GTD/hPDA kick (I even went so far as tracking my time. Then it died down (I just didn't have time to be productive). Now my passion for the productive has been re-illuminated thanks to kGTD and Ethan Schoonover. I have reorganized my workflow (see screenshot) made myself a new hPDA and subscribed to the Merlin Mann podcast (and, of course, I've subscribed to the feed for Ethan's wonderful blog.
I signed up to be a beta tester for OmniFocus (the new task organizer app for Omni, based around kGTD) some time ago, but I have not gotten an invitation yet (although, supposedly they are up to date with everyone who signed up before Memorial Day. It looks like OmniFocus is a lot like iGTD (except it will cost $40, rather than being freeware) but I like the look and some of the organizational features of OmniFocus more. (I must say that I have become a total Omni convert, and to think I was going to delete the preinstalled copy of OmniOutliner that came with my computer).
During my first kick I tried out Joe's Goals but it fizzled out pretty fast. So, today I wrote some new goals and now I am going to try it again (don't tell anyone, but I don't think it will work).
