Awesome. I guess two comments on learn-anything -- is there an easy way for external users to add something? I get it's open source but when you search for something, maybe a "suggest resource" would speed up curation of resources via human indexing.

The other big thing that would be helpful is a "videos" node where you could link to videos on the subject. A lot of people that I talk to struggle learning completely new topics just by reading. Some of the feedback I hear is that a few videos goes a long way to introducing something new, so a videos node could be useful in the overall graph.
