I also agree with what you are saying about Legacy Pdfs, they can be
difficult if not impossible to deal with, especially if these documents have
been scanned from a paper source

The university that I work for has a lot of legacy pdfs. Most of them
are made in Quark or Word, which means that some of them have a
snowball's chance of being accessible. The Word-originated pdfs have a
higher chance, but they still require a lot of time to be made
Why am I telling you this? Because PDFs can be accessible (to a point)
if you are willing to invest long hours and trial and error to make
them both accessible AND usable. PDFs can be accessible, pass the 508
standards and most of the WCAG and they are still incomprehensible with
a screen reader. Text flow is not Acrobat's strong point.
We have a lot of people that would like PDF forms. Not because of the
neat calculating tools that Adobe has worked in or anything else, but
merely because they look prettier than HTML forms. We try to steer
them towards HTML even with the possibilities of accessibility with PDF
forms. This is because we can assure both accessibility and usability
in HTML with a quick creation.
On a good day it takes twice as long to make content that is completely
accessible with Acrobat. That would be a verry good day. Most of the
time it's a struggle. If the content was laid out in Quark you may as
well forget about it.
The pros for PDF accessibility are that it can happen (hypothetically
speaking), it means a few extra steps to repurpose content
(hypothetically speaking) and it's prettier.
The cons are that the user needs extra software (plugins), the manner
of accessibility is still pretty rusty for screen readers (as you
pointed out with the run-on sentence example), and the whole process
still takes way too much time.
HTML requires a browser. Knowledge of HTML or an editing program
(preferably both, thank you very much). Some spare moments to copy,
paste and get everything together.
The best thing about using HTML is that, if you're coding correctly,
you don't have to worry about accessibility because HTML is *meant* to
I would still stress HTML with clients over PDFs because of the amount
of billable hours they will be responsible for paying and the time
you'll be wasting slaving over the readable flow of the PDF document.
