FYI, the link you posted returns a 502. When I manually changed the URL to request http instead of https (the link is https) things worked just fine.<p>Enki seems fantastic. I really like the idea of learning and building skills in small chunks. I feel like so much of my free time is divided up into small pieces (i.e. < 30 mins) but so much existing learning material out there is geared towards focusing on something for at least an hour.
