This system was also designed to distribute the workload of category maintenance among page maintainers. </p><p>However, the category system has since created more problems than it has solved. </p> <meta property="mw:PageProp/toc"/> <div class="mw-heading mw-heading3"><h3 id="Categories_become_editor_hangouts" data-mw-thread-id="h-Categories_become_editor_hangouts"><span data-mw-comment-start="" id="h-Categories_become_editor_hangouts"></span>Categories become editor hangouts<span data-mw-comment-end="h-Categories_become_editor_hangouts"></span></h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Wikipedia:Categories_versus_lists&action=edit&section=1" title="Edit section: Categories become editor hangouts"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Editors have their favorite pages that they watch over and maintain. This includes maintaining the category tags on those pages. Each editor's views on categorization differ. So when you decide to add a large group of pages to a category, some of the watchdogs are bound to object to and remove that tag from their pages. This punches holes in the categories which can lead to edit wars when you try to fill those holes. By contrast, lists are centralized, so you usually don't have to worry about the watchdogs, because you link to their pages without altering their pages at all. In most cases, they won't even be aware of the link. </p> <div class="mw-heading mw-heading3"><h3 id="Categories_do_not_have_a_page_history" data-mw-thread-id="h-Categories_do_not_have_a_page_history"><span data-mw-comment-start="" id="h-Categories_do_not_have_a_page_history"></span>Categories do not have a page history<span data-mw-comment-end="h-Categories_do_not_have_a_page_history"></span></h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Wikipedia:Categories_versus_lists&action=edit&section=2" title="Edit section: Categories do not have a page history"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>When a category tag is removed from a page, and the link to that page disappears from the category page, there is no record at the category page of that link ever being there.

This slows down category filling and category trimming, and can disrupt the brainstorming process that some editors use to create lists. Lists on the other hand can be built rapidly using cut & paste and text editing on the spot. Glossaries on the web can be captured and trimmed down to just the terms, then sorted using a command or program, then a macro applied to format them into links, and then pasted onto a Wikipedia page. Vocabulary and term lists are even easier to convert into Wikipedia lists. It's amazing how many of the links turn blue – Wikipedia's coverage is extensive, but pages often remain undetected or buried somewhere in an obscure category until a good list is made.</li></ul> <div class="mw-heading mw-heading3"><h3 id="Categories_are_not_modular" data-mw-thread-id="h-Categories_are_not_modular"><span data-mw-comment-start="" id="h-Categories_are_not_modular"></span>Categories are not modular<span data-mw-comment-end="h-Categories_are_not_modular"></span></h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Wikipedia:Categories_versus_lists&action=edit&section=7" title="Edit section: Categories are not modular"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li>Categories aren't modular, lists are.
