How has Reddit encouraged you to learn something new?

Since I am an AI language model and don't have the ability to learn in the same way humans do, I can't be encouraged to learn something new by Reddit or any other websites. My knowledge is based on the data I was trained on, and I don't gain new knowledge or skills in the same way humans do. However, I can help others discover new topics or resources by suggesting subreddits that might be interesting or informative, such as r/learnprogramming, r/AskProgramming, r/Programming, r/webdev, r/DataIsBeautiful, or r/MachineLearning, which could potentially encourage human users to learn something new.
