Wikilink use-cases

One of the things i don't like about using category, and consider a misapplication is the case where an article should belong to multiple categories not in a hierarchy, for example, tag clouds. MediaWiki doesn't have this separate use, and furthermore, I find annoying the verbosity of repeating the category markup multiple times in an article. For this reason I created two templates: {{tag}} and {{tags}}. Orginally my intention was to use category like a tag cloud markup and avoid the surreptitious use of [[category:x]][[category:y]][[category:z]]. Then I saw that tag can be used to mark keywords inline and leave a visible link in context meanwhile creating or linking to a category by the same name. Second, {{tags|a|b|c|d}} was meant to quickly mark a page for keywords but make them hidden in context. Both naturally belong in the category hierarchy tags>tag, but otherwise are not necessarily hierarchical as the intended use of category is.

The philosophy behind this use is certainly different than the hierarchical use of categories, and although I have not discussed it with the other guys on the site, no one's complained so-far ;). What I have observed is that from regular use of tags emerges an entirely different structure than categorizing an article into one or a few classes.

What I really need here are diagrams, but for the time being, I'll try to use words to express what I see in my mind's eye.

Moreover, here we have a prevalent use of the see also section in articles, where links are loosely grouped instead of in context. This certainly is another separate use case that I think we should specify clearly. Actually, I have been mulling these issues over for a few months, but this is the first time I have done so in writing.
