A User Propelled Platform or U.P.P for short is an App or website that can only function if the users of that platform become a member and actively contribute content or some of themselves in some way and that if these users were to suddenly leave the platform it would cease to exist as no one would be actively using their membership to keep the wheels of the site turning. Facebook, Twitter, Instagram & Tiktok would be examples of U.P.P's.
