   Format: MarkdownItexWhat is our general policy on the use of "category:" tags on pages? We currently have two kinds of such tags: 1. "meta" labels, like "adjective", "disambiguation", "motivation", or "reference" 1. subject-area labels, like "foundational axiom", "functional analysis", or "group theory". There are only a very few extant tags of the latter sort. Should we encourage the creation of new ones? If so, should we give some guidelines for what sorts should be created? For instance, Stephan just created [[Kan object]] with three "category:" tags of a different sort (I think) than any of the ones we had previously. My first impulse was to delete them as not in line with standard practice, but then I realized that I didn't have any coherent explanation to give of what "standard practice" is.

   Format: MarkdownItexI think that we decided some time ago to have more of #2, but most people haven't bothered. I'm not sure that all of Stephan's new tags will be useful, but since we underutilise them now, I didn't want to discourage it.

   Format: MarkdownItexTwo random comments: I haven't cared much about the "category tags" because the software does not handle them in a useful way. First, pages like "All pages" or the corresponding sub-pages for a given category take forever to load. And then the result looks ugly, for instance in that it has that long list of "wanted pages" with all grey links. This is something to be used by [[lab elves]], but nothing that you want a reader of the wiki to see. Second, essentially the would-be role of tags of type #2 is played by floatic TOCs (listed at [[contents of contents]]).
