Reddit is one of the most popular websites in the world and how Microsoft is opening doors to everyone in its new store Reddit took a logical step and made a Progressive web application and placed it in it. Being a Progressive web app makes it more familiar and feels like a home experience using it for a lot of Reddit users.
