# It is appropriate to point out (really) bad style that would otherwise be off-topic to the question at hand?

Say you have a new user of TeX systems, presumably migrating from more DIY editors. Let's say this user does something like the following:

# Why can't I make the Tex logo?

\documentclass{article}
\begin{document}
I can use \Tex! \\Tex is a lot of fun! \\Latex and \Tex are nice!
\end{document}


Obviously, the issue is a mistyping/misunderstanding of TeX's name, but something more sinister is at play that is completely unrelated to the question. The user is constructing paragraphs how he or she normally would using a DIY editor, by inserting manual line breaks.

Extend this scenario to any and all others we've seen, and you can see why it isn't always such a clear-cut answer. (That is, asked this question, and I would point out both errors.)

Is it appropriate to inform the user that this is bad style, even though it isn't related to the question? Where is the line drawn for such dangerously bad style that warrants such attention?

• I feel like this has been asked before, but I couldn't find a question that fit this scenario. Feel free to close as a dupe if you find it. – Sean Allred Jul 18 '13 at 19:10
• @egreg it is a little more awkward when you don't know the answer to the original question... – Sean Allred Jul 18 '13 at 19:45
