I see a couple of tags that are similar and appear to not be used appropriately.
code has no description and over a hundred questions. It seems that many of the uses for should be code-formatting or inline-code. Many times it's just slapped on a question that's talking about source code of some sort. Worse, it's even used on a question tagged faq.
source-code is described:
The source-code tag should be used when asking about the source-code that generates the SE sites, including all its features.
That seems odd to me. It's not like Stack Exchange is open source or that they're otherwise sharing the code. Ignoring that for the moment, it seems to be improperly used in much the same way as code.
Anyway, what would be a good way to proceed to clean this up?
