Does anyone have a feel for the differences between Storyspace and Tinderbox? I'm primarily interested in notes for writing. Technical writing, which is probably my only credible excuse for picking up a pen, and short stories and novels because there is a noisy Walter Mitty in my soul.

I would like to have a map of some sort - mind map, timeline, corkboard, something with references to notes - where a note can appear in more than one place.

That way, a note appears everywhere it is referenced and editing it in any context updates the source for the note.
