I've been using Org mode for sometime now and I should say that it's one of the best productivity enhancing tools for me. It's helped to get things organised so fast that I find myself tasking thinking of org mode when planning something.
If there is anything that needs to be done in the next few days, I usually plug it into the org file and then forget about it(err, not that way) and let emacs remind me of all the things on my plate as the deadline approaches.
And Carsten Dominik has been brutal in his releases; I mean, bug fixes, new features, re-writes, the works, it's really amazing seeing the point releases come out. It's so fast that I had to switch to a monthly update of org releases i.e. download the org release only once a month.
It's frenetic. and absolutely beautiful to watch everything happen working on a simple text file.
I just don't know how he does the kind of output on implementing things on org mode.
Whatever he's doing, it's an enormously useful for the rest of the user community.
