That's the link I submitted. For some reason, when I submit .pdfs to news.YC, I get redirected to Scribd.
YC auto-scribds PDFs, there was an Ask YC poll about it last week. I guess the result was to leave it the way it was. The problem with your link wasn't that it was to scribd, but that scribd couldn't import it as a PDF.
The majority of people wanted some form of Scribd on the site and the majority of people also wanted a change in how it is implemented.
