There is an increasing number of questions on the parent site which are being tagged with tex and latex. Although the second one could be justified in some cases, the first one doesn't have any sense in a site specifically devoted to TeX questions (it is like tagging a question programming in stackoverflow.com or maths in mathoverflow.net). I think the tex tag is redundant and should be removed.
If one could guarantee that the 'tex' tag was used to mean 'this is a question about the bowels of TeX, if you don't know the difference between
\edef then don't read any further' then I would argue that there was a place for it. However, the parallel universe where that happens is nowhere near this one so I second the proposal.
I actually think the
latex tag is the useless one. Most users coming to this site are probably dealing with LaTeX and, by default, our answers should be as most LaTeX-friendly as possible, using robust macros and packages. And only if the question is tagged as
tex (or maybe
tex-core or maybe
macros or maybe something else?) we know that the poster has some TeX experience and is confident with using low-level commands.
I have never used plain TeX, only LaTeX. Maybe the tag should be plain-tex? For those who are not using any metapackages, or what to do something cool using plain TeX.
Is either of them useless?
What if I want to ask how to do X in LaTeX? I'm not interested in answers talking about how to do it in regular TeX, or LyX or any other variants, just LaTeX. How should I tag it?
Likewise, what if I'm interested in how to do the same thing in TeX specifically? A LaTeX answer is no good to me.
Aren't both the tags justified then?
The problem obviously becomes enforcing this discipline (so
[tex] doesn't end up on every question)
Or perhaps we should use [latex-only] and [tex-only] to indicate questions about those specifically?
I think it is true that most questions will be LaTeX related. (I've tagged some things with the latex tag, but not without some concern.)
However, the tex tag is needed, I think. I answered this question in LaTeX terms, then saw the tex tag, and deleted my answer. I've also commented on two other answers along the lines of "LaTeX answer to TeX question". I wasn't sure that it was a TeX not LaTeX question until I saw the tex tag.
Reading the existing answers I propose to have the following tags:
tex-hacksfor meaning "I know about
\edefso TeX hack-ish answers are fine for me. But hey, I'll also welcome any LaTeX answers too!"
context, etc. for meaning "I only care about answers for this particular set of macro extensions. Don't bother me with anything outside of this scope!"
tex tag should then be ditched and replaced with a more specific one, i.e. either
