Emma: rating tree Reviews

Developer speaking here, but, while its still very early beta, I think this program has tons of potential for helping people learn new ideas and finding the best examples on the web of a given topic. Other uses include thought process examinations and core belief matching. The math example on the site is just the basics of what a teaching/learning sub-tree of emma would look like, with multiple ranked sources to help define and explain a topic. I'm hoping to add separate rooms for users, like personal home pages where they could add links to whatever nodes they want. Like a favorites system.
