I plan a presentation on a TeX conference, which should be suitable for the very experienced audience.
In the sense of this question:
If you would like to convince TeX hackers of this site, to win new expert members, which question would you showcase?
Though votes to questions show quality and popularity, I'm looking for expert-attracting content, so I look forward to reading your personal recommendations, optimally with a short reason.
Since I'm a newbie, I still have difficulties on spotting TeX challenges, but I have a suggestion: question could be picked up based on their tags. E.g., the top 5 tags are:
These tags could act as a "community thermometer", because we can see what our members are looking for. We could also play with Data Explorer and try to find any relations on questions and answerers.
IMHO a great showcase would be a list with all packages based on answers given here. That also includes the amazing "From answers to packages" repository in Launchpad.
I also support Raphink on all of his suggestions. And I want to promote suggest my own question, which Martin Scharrer provided an amazing solution: Creating a zebra effect using listings. :-)
From seeing the discussions on the LateX mailing lists in the past, I think the discussion on the river detection algorithm and defining their badness is a subject that might be of interest to TeXperts. There's no definitive answer just yet, but they might be interested in participating.
Since you are going to India, I would consider asking a foreign language unicode question.
For example, in order to use a "Sinhala" unicode font I have to use a transliteration scheme. I use the site http://www.ucsc.cmb.ac.lk/ltrl/services/feconverter/t1.html to do this and then cut and paste the unicode phrases into the LaTeX document. This is a time consuming and frustrating process. (A simple code and the associated output is given below.)
\documentclass[12pt]{article}
\usepackage{sinhala1}
\usepackage{fontspec,xltxtra,xunicode}
\defaultfontfeatures{Mapping=tex-text}
\setromanfont[Mapping=tex-text]{Hoefler Text}
\setsansfont[Scale=MatchLowercase,Mapping=tex-text]{Gill Sans}
\setmonofont[Scale=MatchLowercase]{Andale Mono}
\title{සිංහල අකුරු - Sinhala Letters}
\author{සැලෙන මනස විසිනි - by Wondering Mind}
\date{}

\end{document}

I would like to know how to type the correct unicode directly into the LaTeX document. (As you can see, the first line of the code is different from the output. The typed code is incorrect, however, the output is correct. In other words, not only I cannot type directly, but also, I have to paste the incorrect code to get the correct output. Also look at the title.)
I hesitate to ask this question here as I do not think there is a critical mass (of people) who uses Sinhala. However, you may find takers in India.
There are questions that are very edgy and lead to changes in edgy software like LaTeX3 or LuaTeX. These questions should be interesting to TeXperts.
The one (not answered) about notes overflowing might be interesting, too (sorry, mostly choosing from my own questions, as I know them better).
