One of the other things I started was the design pattern for the ⭐️⭐️⭐️⭐️⭐️ star review and rating system that you see all over the Internet in various products.
Next time you give your @Uber driver or @Airbnb host a 5 star review, or looking at yelp to help you find a restaurant, be sure to think of me. We were the first to do it with the iTunes Music Store.
