Am I missing something obvious on scribd? I saw no way to download the original PDF on the scribd page. I was as annoyed as the original poster when this paper (HPL-2007-193) was on HN and I tried to save it so that I could read it later. I ended up doing Print->Save As PDF from scribd. When someone later posted a link to the original PDF, it was much nicer looking, smaller in size (4MB versus 164KB), and had the original metadata (e.g. authors, description).
