I have never been able to understand the Slack fetish most tech people have. IMO MS Teams is feature-wise better in most cases. Especially functionality for formatting posts is far better in Teams.
"LaTeX is not a word processor! Instead, LaTeX encourages authors not to worry too much about the appearance of their documents but to concentrate on getting the right content."
IMO, the only people that use LaTeX are people who are willing to trade the convenience and productivity of using a sane document authoring format for the warm and fuzzy feeling you get when you use an outdated piece of typesetting software that is a) hard to configure, b) hard to use and c) produces output for the least useful reading platform available (paged pdfs).
