What I like about topic modeling is that while you don't get theories or generalizations or neat simple taxonomies, you get information you can use. Claudia Ng writes, "I find that surveys and live interviews have a performative problem: people sometimes tell you what they think you want to hear. NPS scores compress everything into a single number and lose the nuances. What people actually type when they're trying to get something done is neither; it's messy but it's exactly what you need to shape a roadmap." One plan I have for the future is to do a topic model of my newsletter posts over the last 25 years. Should be interesting.
