Node and browserify enthusiast, consultant.
Thanks, we are definitely going to be continuing on with this project. And as you've pointed out, scraping the READMEs and integrating them with the main site is definitely on our job list.
However, I'd like to take this time to explain the rationale behind the text messaging. We believe SMS quiz questions are really valuable, and why we chose to debut that feature during the hackathon - it's a better way of learning. When testing is distributed over a long period of time, and happens out of the blue, you tend to retain information better. So we didn't just do this because it's a fun feature, we did it so our users could learn more effectively (check out the science link on our main page for more about this).
Lastly, we apologize if the messages didn't reach you, and have adjusted the judging instructions to indicate the quizzes may not be received outside the US & Canada (for your information as well, we used the Twilio credits we got as part of the competition to make this happen).
Thanks again for your comments and taking the time to evaluate tut.
