I don't know whom this is actually making fun of -- if I were hiring, I'd consider the presence of a cover letter with my name on it to be of far more informational value than a resume typeset in LaTeX. The cover letter would actually show me that the person made some modicum of effort to apply to my company; the LaTeX wouldn't give me anything I wouldn't be able to tell from the rest of the applicant's resume. And there's no way it's worth more than "started own company".
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.
