Ripple is a social app where posts reach a wider audience based on their popularity. New posts are only visible to users in the local area, but as a post gains upvotes, the area it is exposed to increases. The poster can view a map showing roughly how far their idea has spread. As with many forums, users can accumulate karma showing the net upvotes on all posts and comments they make. The algorithm that determines what posts are visible guarantees that a user will see the 25 most relevant posts to them, no matter where they are. As the app gains more users, it will become more difficult to reach the same area, however the likelihood of reaching the same number of users remains roughly the same.
