Why does hypertext make structuring your document more complicated?

Because readers can now:

• move sequentially
• jump around (skimming content)
• look for a specific piece of information

But readers can do that with a book - why is hypertext so different?

it doesn't just allow a non-sequential approach, it encourages it

• links are enticing
• easier than looking something up in contents/index - just click on it!
• easier to keep your place - look at something, then go back to where you were
• on the web, a subsection can be reached from anywhere (via bookmarks or a search engine), not just from the main page
