I never noticed the descriptivism tag until today, when it *was** used for this question which is now closed. At present, there are ten uses of the descriptivism tag on the site, including the closed question. I considered drafting a wiki entry for it, but I truly don't know what the intended usage is. Might anyone provide some some suggestions about how this tag should be used?
SE engine's spell-checker red lines descriptivism. This doesn't mean that the tag is incorrect or bad! I mention the red lining only to emphasize that the word, or term, is somewhat unusual for a tag in the context of this site.
*The closed question no longer has the same tags. The descriptivism tag count equals nine.
