I just was checking via google-- who still uses LaTex?

When I was still actively in the game, so to speak, most graduate students at least in engineering and science did. I worked with a lot of AFIT (Air Force Institute of Technology) graduates  when an aerospace sort. They too all seemed quite versed in LaTex. 

But I'm old history, and was surprised to read and see from your example that science/engineering types still use it.
