After taking a look through posts that had this tag, I found that quite a few of them either get closed or migrated to meta. Except for users who have been here for awhile, this tag seems to suggest to new users that posts for "best practices" or "resources" fit on the main site.
For example, the previously closed question here uses the "learning" tag.
The tag description currently reads:
Improving your proficiency in the Japanese language.
Could this description be improved so as to not be open-ended? Correct uses of the tag tend to consist of those relating to the Japanese society, school system, etc,.
EDIT: It is probably best to have a list of questions that use this tag appropriately and those that do not. I made links to some of the questions that might help define the tag. If any links should be added, removed, changed, or switched, please comment.
