I'd suggest the 5 best quality courses, and a "More.." button. The "buzzfeed" comment elsewhere leads me to believe the other guy picked one of the courses that was not curated as well as what I chose, which is the basis of my suggestion.

I've received one highbrow email thus far, and I am happy for reading a good quality blog post instead of having to sift through serps and junk blogs for myself, and also to learn about some new resources in my area of interest. I totally get the one thing at a time, 5 minute per day commitment, I think it's a great idea.
