The potential with this site is making the hair on the back of my neck stand up. I feel as though this could really morph in to something that not only allows us to just track thoughts on a topic, but through social features see the effect of the thoughts we publish on others and how they might trickle through other streams to perhaps influence something big.
There are so many possible applications of this tool swirling around in my head that it's hard keeping them all straight. I'm really excited to see how the site evolves and how people use it moving forward.
