Underutilised but important category? DeleteWhenCooked
I suggest all pages with Soap, Rest (RestArchitecturalStyle), etc should be tagged with this category.
- And yes I have seen PleasePleaseDontCategorizeEveryPageOnWiki, but I think this is a very important category.
- prompted by seeing the page JabberAndSoap without appropriate categories at all
Changed mind. I have created CategoryWebServices (itself being category as CategoryMessagingServices) instead.
