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.
Since you've got everything in a git repo it would be really easy to diff/fork/merge other folks' knowledge bases.
Probably not useful to you personally since there aren't forks out there yet, but it's cool to see you've got all the infrastructure in place for some kind of "mind meld" feature.
