I’m glad I’m not the only one who doesn’t like the format. On Mac OS X, by default, when you want to view a PDF on the web, you have to download it to the disk and open it with Preview or Acrobat. You can enable Quicktime to display PDF files in Safari, but it will only display the first page. There’s the PDF Browser Plugin that is slow even on my Powerbook, and has big useability bugs.
What Jakob Nielsen doesn’t mention is how complicated it is to edit PDFs. I have a lecturer who puts all his lecture notes online, in PDF, in Comic Sans. Uugh. And there is (almost – pdftohtml) no easy, quick way of converting all that to XHTML and display it in Lucida Grande or Gill Sans, as I do with those awful Powerpoint “Presentations”.
Why can’t lecturers publish their slides in a readable format? What’s wrong with HTML?
