According to Raskin, too many people working on hypertext have concentrated on mechanisms instead of on the user interface. It is necessary to look at the entire spectrum of interaction and to do continuous user testing.

Granular Addressability in HTML Documents - ON THE FLY

The issue of citing particular phrases in web documents has also been raised previously,with paragraph-level identifiers added by the purpleslurple29 tool,

Also, I would like to create a roll your own PS bookmarklet builder that will allow one to specify for example where the anchors should be placed (beginning/end of paragraph), whether to use numbers/graphics, link/alink/vlink color(s), option to show/hide certain elements or include toggle button, etc.

Matthew Schneider developed the first HID implementation which generates purple numberson-the-fly for HTML and text documents which he published in 2002.

PurpleSlurple is a transcoding service that reformats Web pages on-the-fly to create granular addressability in document elements on EXISTING Web pages.

Another handy tool is PurpleSlurple, which provides granular addressability for any existing web page. In other words, it inserts links for paragraphs and headers, allowing you to reference specific sections of text on a given page. Each “slurped” page gets its own URL, as does each individual element that has been anchored with a reference number. It’s primitive, but could come in extremely handy. For bloggers, this provides another way to reference a particular passage in a long web document. Just slurp the page, then link to the specific section.

Wikalong makes it possible to write notes in the margin of a web page (something we take for granted in paper books). Reviews, rebuttals, conversations, subversive commentary, a “roving weblog,” or just plain old notes – all of these are possible in the little sidebar wiki notebook that Wikalong places to the left of any web page you go to.
