Scapple is the software equivalent of how I work out my rough ideas on paper. (If I didn't hate the word "brainstorming" so much, I'd probably call it brainstorming software.) When I'm in the early stages of any project, whether that's a writing project or a software project, I tend to throw a bunch of ideas down on a big piece of paper, spacing out as-yet unrelated ideas, clustering related notes, and drawing connections between them, trying to work out how everything fits together.
