i love the idea behind scapple. It's like taking a whiteboard into the cloud and gives you access to it wherever you are. As a team we used scapple to collaboratively brainstorm about new ideas, plan future projects, and structure information about previous projects. We found it to be invaluable when collaborating across different disciplines, offices, and time zones. We also used it to help us get organized and stay on track with project planning and progress tracking. I would recommend using scapple if your goal is just keeping all of your notes together as one place, so they're easily accessible whenever needed (and ideally searchable). For more formal collaboration purposes, such as project management or research, other tools might be better suited.
