Being a computer science student and having a lot non-coding-assignments to do, I am proud to say:

I love LaTeX!

I still use it to make all my doc that Markdown can't cover

Since I discovered latex my life has changed latex is love latex is life

A made my seminar presentation in Latex in 3rd year. It looked very professional.

It feels like programming instead of writing! :-)

Would you guys point me to some uses cases and a quickstart? :)

I find it takes away the feeling.

@mundo03 use case for me was to write a seminar report (which is usually written in Latex) and then to create a presentation for the seminar in latex (because there was lots of mathematical stuff in the presentation as well).

I referred documentation of ShareLatex:
https://www.sharelatex.com/learn

Or start with markdown, use pandoc to convert to LaTeX, tweak LaTeX.

I mix Markdown and Mathjax, problem solved !

Sometimes they expects me to know and use word - but after 5 minutes fighting with the formatting I feel like I have to quit.

For most of my use cases markdown is fine. I just played around with LaTeX.

I understand
