Some users create tags while adding question; some are highly useful and some are simply meaningless. Do SE have any mechanism to encourage users to add tag wiki as well, on creating tags?
Esp. see this question In conference review process, what do “author response” and “author notification” mean? What actually the tags (wording) (dates) (call) mean?
So, if the tag creator him(her)self propose a tag wiki, it is good for the community.
