Here is on suggestion. Feel free to suggest others in the answers section, if you have alternative suggestions. And then perhaps after a while we can decide on one course of action.
Based on Paul's inspection of the questions that are tagged as code, it seems that it might be appropriate to make the tag about typesetting code for (other) programming languages.
If everyone likes this idea, then we should add that to the wiki summary and untag the questions that don't fit the category. (Doing this slowly over time, of course, so as not to bump everything to the top of the active questions list.)
Comments/edits amending this suggestion are more than welcome! Or, again, feel free to suggest an alternative!
