To PDF or not to PDF

This week's post from Jakob Neilsen has been causing a few ructions.

He headlined "PDF: Unfit for human consumption", and then went on to state the obvious:

"Users get lost inside PDF files, which are typically big, linear text blobs that are optimized for print and unpleasant to read and navigate online. PDF is good for printing, but that's it. Don't use it for online presentation."

I think we've known about this stuff for a while, Jakob.....
