Great site, I think I had seen it before (in Reddit?). I like it just the way it is, no nonsense carefully curated list of things to learn online.

I feel weary of changing any of this, but if you want users to come back a good feature would be listing the starting dates for upcoming courses. Coursera and Udacity courses have specific launch dates, you can use this information for a more "what do I want to learn next week" experience.
