This community has decided that asking for links to resources is off-topic, for understandable reasons (e.g. we're trying to be 'the resource' ourselves, and there's a risk of link rot). We get questions occasionally where our answer (or close comment) is along the lines of "you should go and learn some theory". Would there be any enthusiasm here for creating a single, curated question containing links to good resources? Has there been any discussion about this already? Maybe there's a good list off-site that we could point people to? Or maybe we don't want to get involved in this kind of thing?
