> Personally, I'd like to see a concept map of essential computer science topics combined with some of the top papers and books that cover each. It could be implemented as a curated collapsable directed graph.

I've tried building one of these before, both for CS and for Maths. Funnily enough formatting, displaying and making it accessible (whilst retaining enough data) was the time-consuming issue, despite all the tech around for handling graphs. :/
