Tags related to languages
It has came to my notice that there are some language / country specific tags floating around (actually, there are a lot of posts using them).
To my idea tags should point to a specific subject, concise and consistent (not ambiguous) and useful so that the people following them can easily find related posts and help or be helped.
I would say those tags are useless and the posts created with them should be covered by the internationalization tag with some other that better focuses the issue, ie: fonts, ibus, keyboard-layout, etc.
Should we keep those and allow them to exist or clean them? Why? Who are they helping there?
