What are the key differences between traditional documents and websites?

Traditional documents -- if they are printed -- have a different 'look and feel' than those available digitally.

Margins, fonts, white space -- all clues to the reader for ease of reading -- are different, because the reading surface is different.

Web sites are free-form, free speech, meaning that no editorial, verification or oversight is required, and often none is provided for content on a site.

Traditional journalism, book publishers and other stakeholders in the 'information industry' build brands centered on correct spelling, grammar; full disclosure of conflicting interests; fact verification and so forth.

When one is not connected to the internet, Web sites are not available, unless they have been ported to a reading device, then they can become outdated.

One can carry a traditional book, magazine or other publication into the wilderness, store it on a bookshelf, and over time, pass it along to another in its physical form.
