There are a reasonable number of AI stories submitted here, but no good tag for it. Some fit in
cogsci, but a lot of the AI stuff filed there is a bit of a stretch to call cognitive science, and just submitted there for lack of a better place (example, example). And machine learning often gets misfiled under
ml, which is supposed to be for the ML family of programming languages.
Besides being useful to those of us interested in AI, it could conceivably also be useful for people who are bored of the AI hype and would like to filter it. :-)
