I've been using HackerSmacker for a while to tag AI-related and non-AI-related submissions.
I find, depending on the time of day, 30-50% of submissions are about AI. Also, Users who submit AI-related content tend to also submit non-AI-related content - those I tag for non-AI-related content almost never submit AI-related content.
