More people are keeping their files digital and don't intend to print. It's preferable that we simply share links to a webpage or cloud document that is meant to be scrolled through.. but many professionals still insist on emailing file attachments because they are comfortable creating Word Docs or Google Docs, but have no idea how to create a webpage.
PDFs continue to be the file format of choice for portable documents. Some document editing apps, such as Google Docs, have evolved to allow pageless document view - functioning like an endless scrolling web page or an eBook. Exporting a long document to PDF can be jarring when suddenly important content is interrupted by an awkward page break. It's time for Adobe Acrobat to evolve to allow files to be exported as pageless files, like a continuous scrolling eBook. The most efficient way to navigate this kind of pageless document is with "chapters" indicated by headers (H1, H2 etc). This would also encourage more people to learn the correct heading hierarchy. An emphasized scroll bar should indicate how far along you are in the document. Ideally, the reader should be able to increase font sizes, bookmark sections and add comments. To reduce confusion with PDFs designed for print, you can apply a file extension.PDFx or .PDFd
If Acrobat supported this, it would encourage the most popular document editors to favour designing for screen reading.
