PDF is a separate file type like MP3 or SWF, rather than one of the choices for an HTML file. Apples and kumquats.
I have converted some of my guides into a downloadable pdf file on request. I realize they are different but in terms of rankings a .pdf file gets a fast pass, there just aren't nearly as many of them online.
