I noticed not long ago that i cared more about some of the characters in my game and their visually tracked progress mostly in part of a formulated concept that makes me invested in these characters. I broke my gaming habit to develop better habits like reading and designing and general learning. I heard duolingo mention in a speech by bill gates and thought, if its gotten that much buzz it was probably something to at least check out. So its free and uses the game layout to make myself interested in my own skills and development/progress, a much worthier cause and better use of these manipulation systems. I hope to see this site develop further and possibly get involved with the community and want more company's like this helping people develop skills.
