Let's see how deep I can go with this.
== Categories vs namespaces ==
There are two features which both implement categorization: categories, and namespaces.
Namespaces:
- One each, or none (Main).
- Searchable: While searching, you can limit your searches to certain namespaces.
- Not searched (by default): A regular search will not search in namespaces other than (Main). A MediaWiki setting can add more namespaces to the default search.
- Requires typing the namespace to link to it.
Categories:
- Many.
- Not searchable (but see https://www.mediawiki.org/wiki/Extension:SphinxSearch)
- Searched, if in the searched namespaces.
- Does not change the page name, so does not need to be typed out.
