A few years ago I had the privilege to work with Information Science professor Filippo Menczer at Indiana University, and created Fakey, a media literacy mobile app and website that got some traction and news coverage.
Fakey is a game with a purpose where players are placed in a simulated social media news feed and are tasked with disambiguating between high-quality news and lower-quality news such as fake, bias, conspiracy, junk science, etc. The players are constructively directed towards creating a good social media experience where good information is shared and false information is fact-checked. We created this game for media literacy as well as for research in uncovering patterns in the way people interact with social media news feeds.
