Does anyone have a good tool for jotting down ideas and rearranging them? I find that word processors are not very good for this, because they are more concerned with formatting than manipulating units of text. Simplicity is paramount.
Org-mode in Emacs is brilliant for this. Write things as outlines, shift sub-trees around trivially, fold (hide) and un-fold (reveal) subtrees, embed links within your outline, export to text or HTML when needed.
If you don't know emacs and you already have Word you could use the outline mode of it. I have used it in the past and it works pretty well. I haven't sat down and learned emacs so I have yet to try org-mode but I hear that works well too.
I have yet to find a truly great outlining program yet. (Note: I plan on learning org-mode emacs but I am a vim guy so the initial inertia of learning it is high.)
