I am just an occasional visitor here, but I thought I should take the time to revive this discussion and provide a readers point of view:
The code tags are a mess.
I was looking for interesting questions regarding source code formatting and highlighting within latex documents. I came across sourcecode, but realized soon that most of these questions (but not all) were about the latex source code itself, not the inclusion of source code in documents.
So I noticed there is a tag code. That has to be it, right? Because what else could that be. But for some reason it seems to be exactly the same as sourcecode and all the questions are about the latex source.
Many questions are tagged one of the both, some even both. But I still haven't found a tag for the inclusion of source code yet. :)
I don't want to tell you regulars how to run your site, but I think it would be helpful to clean up these tags, define clearly which tag is for what and then put a clear description in the tag wiki, pointing users to the other tags if that was not the tag they are looking for.
