Is it worth learning Latex just so that (some) people who see my resume will recognize that I took the time to learn Latex?

I use LaTex a lot. That said, I have a few problems.

Nothing is as bad as someone who decides he is going to use Latex for general documents - such as composing tests or any type of document.

Why when people use LaTex their brain automatically shuts down? In college there are people who give extra marks if a report is done in LaTex. I thought that if a report looks nice (no matter if you've done it in FrameMaker or Word/OpenOffice) it is all that matters.

LaTex is nice - but it is not the holy grail that everyone pretends it to be.
