Maybe my problem is I don't do complex enough work to warrent a tool like this (I'm still a BSc student). I do use emacs for almost everything already but I don't use anything for organization really because it just seems like a really complex way of just setting a reminder somewhere
I use org mode and my work is fairly simple. Never underestimate the power of being able to go back to your thought process on something you did 1, 5, or even 10 years ago.
