WikiBrains is a cool site that allows users to create a brainstorm in the style of a wiki. It's pretty interesting in the way it works like a search engine but starts mapping out terms that you type in, and then connects them. Also, users can browse, share, and edit other brainstorms (hence the wiki feature).
I highly recommend checking out Wikibrains by clicking here!!!
