Dustin McIntosh analyzed user interactions with a product to understand different user types and how to improve the user experience. The analysis found that users can be classified as novices or experts based on characteristics of their SQL queries. Novices tended to make more SQL errors than experts. The analysis also found that some users who completed the tutorial did not continue using the product due to frustration, likely because the tutorial did not provide a good onboarding experience. Personalizing the product response based on whether a user is a novice or expert could help improve the user experience and reduce churn.
