Hello all, I'm currently looking over expl3 as a whole, and examining what is useful and what is there for historical reasons. One thing that would be very handy is an idea of where expl3 is being used. I know about my own packages (siunitx and noets2bib), fontspec and xfrac, and of course the higher-level LaTeX3 stuff. However, what would be handy would be a more complete list. -- Joseph Wright
