I’ve never once heard of anyone reading pdfs for non academic reasons.
I’m a QA lab tech. I read PDFs all the time.
Now we care if you try to read PDFs on eBook readers.
I’m just saying this as someone who has a small library of ebooks, and who has had to convert a number of ebooks or fanfictions from PDF. It’s annoying and the formatting frequently gets all out of whack.
But my office has plenty of fillable forms and such that we submit electronically, and the majority of them are PDF. I’m the one who is responsible for updating them when a new version is available or correcting them when they need to be adjusted.
