@Rainbolt I'm sorry if my question was unclear. I wouldn't have asked if anyone objects to collecting problems and solutions. I only mentioned only the solutions for a reason. Likewise, bullet point was intended to mean that we some sort of dummy problem. Surely "Do we have an existing Stack Snippet which generates leaderboards for code golf challenges?" isn't an actual problem - as you said, it's way too specific to be a problem. It just provides a place to post the snippets as answers.
But if you read the question with a broader meaning, I'm fine with expanding the scope of the question …
