Can you add some normalisation topic (or combination / average of several topics) like "linux" or "javascript" or something that's been around for a long time and hasn't really had a hype cycle recently?
It's interesting to see how AI/Crypto relate to each other, but e.g. for sentiment analysis we would need to check if maybe HN got more negative _overall_ or if it's actually dependent on the two topics you chose
