I host brainstorming sessions with usually about 6-8 people involved. We have a white board and 3-5 sheets of butcher paper on the walls. I'll moderate and post everyone's ideas around the room, grouping as I go along in physical locations on the white board and paper; in this manner I'm able to control the brainstorming simply by pointing or walking to a specific area in the room. The trouble I faced after the session was over was how to record all this info I'd collected while retaining the simplistic and intuitive grouping format. I used to copy down the whiteboard and take the butcher paper with me back to my desk where I'd copy every item to a different page of a Word doc that I could then email to the group members for refinement ideas.
Obviously, scanR is just about the most perfect solution possible. We have digital cameras all over the office and now I just snap a few shots, send them along to scanR, and forward the pdf's to all the brainstormers. I've actually found that the pdf versions have a certain emotive quality that was lost in the Word documents! I love it!
