Well, 10 years ago, Norman predicted something that is happening today: “In hypertext, actual numbered footnotes will not be needed, but some sort of signal is still required. With hypertext, the signal that more information is available can be given through color, motion, or typeface” p.213. Nowadays, on the web, we find thousand of text with hypertexts and they have that signal he was talking about: underlined words, highlighted, hotspots, and reactive areas, that help the reader to identify the hypertext.
I wanted to recall what I just said because I don’t think he was totally negative to the use of hypertext. At least that is the idea I got out of the whole text, maybe I can be wrong. J Having that said, my thoughts about hypertext are that of course requires more work from the writer, but it provides more independence to the reader. It allows him to choose what things does he/she want to go deeper or not.
