What was once a conference room exercise can now be done on-line at a site called Brain Reactions. This is a pay service that allows for private brainstorm rooms to be created. A free test drive is available which permits one brainstorm with 5 participants.
Additionally, the site also offers a space for open brainstorms (free). These are seen by all who check out that section on the site. I thought it would be interesting to post a question and see what kind of response it generated. You can see it and participate here.

Someone just might have a good idea to share. Scientific research? No. But hey, you never know what we might learn.
