Map the Mind

Have been using Mind42 for "thinking aloud" and collaborating on ideas. It captures thought processes, and aids iterative, in fact an "continuous design cycle". Very useful for ideating, tracking, and having a bird's eye view of whats up. I'm even using this for todos on the home front, and it works as well. The best part is how easy it is to collaborate on or share the evolving ideas/concepts with others contributors.

You can also export the map to a variety of formats - FreeMind, for instance

Really exciting product after a long time.
