I’ve been making lists of forgotten articles - articles that were created 10+ years ago but have no incoming links from other articles - using a tool that lets you run inline SQL queries on a copy of Wikipedia: https://en.wikipedia.org/wiki/User:Dreamyshade/LonelyPages
The game is to find other articles that should link back to them, and add those links. Sometimes you find duplicate articles that need to be merged, or hoaxes, or self-promotional articles to delete. Sometimes you feel like a caretaker in the Library of Babel.
