On the other hand, LaTeX should almost be a required skill for developers and dev managers. If you use it rather than M$Office, your development docs can be source controlled, easily diffed, and otherwise gain all the benefits of code! Design docs, data flow diagrams, architecture layouts, data models, &c., &c. can all be done in LaTeX will look great.

I disagree, I've been working on business-area applications for 5 years now and not once have I said to myself, "Man I wish I had some Latex knowledge to work on this document!".

It's just non-existant unless you actually need the math notations and whatnot.

Of course, if the documents don't need to be edited by their recipients, PDF is even more of a de facto standard than .doc{,x}
