A while back, people asked about whether to include LaTeX formatting on PCG.SE. The answer was generally no, because people believed that the filesize was too big and had too much of an effect on loading time.
But then Puzzling.SE got LaTeX support added, which was a few months after that question was last updated. I'm wondering whether it would be a good idea to reconsider bringing LaTeX to PCG.SE, since a lot of the programming puzzles I've personally written would definitely benefit from LaTeX notation:
Note that some of these questions also use code notation that should stay code notation; however, there are significantly many bits and pieces that would be preferable to format in LaTeX.
