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.
