Hey guys!
    I've recently joined Khan Academy and am now hooked!  The positive feedback in the form of points and badges really has gotten me focused on learning.  I'm sitting here doing all the activities and missions I can to get more and more points.  

WE NEED EVEN MORE.  Perhaps a level system, or rankings.  The constructive competition does do its wonders in a learning environment.  

Or does anyone happen to know is this is in the works?
