I dunno about all this HTML vs. PDF technobabble stuff.

What I do know is that when I send out job applications by email I write the cover letter in the body of the email message and attatch the resume as a PDF file. That way it shows up nice and professional lookin like I published it, rather than just being a document file and opening up in some kind of word processor window for them, or an HTML file and opening up in a browser window; either of which is eminently less cool than a nice uneditable (unless they have the full version of Acrobat) PDF that looks like an actual piece of paper but on the computer screen.
