# Is the following a suitable question for TeX.SE?

I have an idea for a question, but it's rather non-standard, so I thought I'd check here whether it's suitably on-topic to post.

Title. "Find-the-error puzzles in LaTeX!"

Answer. For a bit of fun, and maybe some pedagogical benefit too, each answer to this question contains a short LaTeX document that gives a compilation error. The challenge is to try and spot the error without compiling - just by reading the code. And of course, no giving solutions in the comments!

\documentclass{article}
\usepackage{tikz}
\newcommand\startpoint{1,1}
\newcommand\endpoint{3,3}
\begin{document}
\begin{tikzpicture}
\draw[red] (\startpoint) -- (\endpoint);
\end{tikzpicture}
\end{document}


• Another possibility is to start a new series in our blog. :) – Paulo Cereda May 25 '13 at 12:00
• @PauloCereda That could be fun :). Could you tell me a little about how might that work? – John Wickerson May 26 '13 at 16:35
• @JohnWickerson: I'm not sure how it might work. :) A possible approach would be a nice blog post with some introductory text, the code, some explanations on why the code doesn't work and the solution. I think the post should be self-contained, that is, everything should be in place (code and answer). The series could be something along the lines of Spot the error. :) We could get feedback from all other bloggers as well, so we could come up with a nice format. – Paulo Cereda May 27 '13 at 13:22
