    Hey HN! I've built Curiosity of the Day to help people increase their knowledge of the world, one day at a time. Each day, it presents the user with a new fact or piece of knowledge about anything from history and science to art and culture. I’d love to get some feedback on ways to make the app better, and any other ideas on how to make learning more fun and engaging.
