While working on https://meta.superuser.com/q/8402/393570 I have come across the tag [tag:chinese]. There are quite a few questions on there of varying quality.

What is it for, why do we have tags specifically for human languages?

Similarly I have found the following language tags:

- [tag:Spanish]
- [tag:German]
- [tag:English]
- [tag:Japanese]

Would these be better served being retagged as [tag:localization]? It is quite possible that I have missed the point of these tags.
