From DSC:
After seeing the sharp interface out at Adobe (see image below), I’ve often thought that there should exist a similar interface and a similar database for educators, trainers, and learners to use — but the database would address a far greater breadth of topics to teach and/or learn about.  You could even select beginner, intermediate, or advanced levels (grade levels might work here as well).

Perhaps this is where artificial intelligence will come in…not sure.
