Several users recently added a newly-created category called "Determinant" to many articles. I removed it from all of the articles and deleted it.
Why? Because we already have a category for this purpose. It's called "Purgatory", and there's no need to create a new category with the exact same description and add it to articles. It doesn't make navigating the wiki any easier. It's important to look at the categories an article belongs to before adding new ones - categories are supposed to simplify navigation, not complicate or obfuscate it.
If anyone has questions about this decision or policy, please let me know.
