JKN - Is the last annotation tool I will review?

Another web annotation tool for everyone - JumpKnowledge(JKN). JKN works pretty much similar to other tool like SharedCopy but with differences. Speaking in the plain old commentary fashion - JKN works with https, framesets, supports multiple pages in a single annotation, and has an optional Firefox button that can annotate password-protected web pages and JavaScript-rendered pages. Besides that whenever you add comments with JKN, the underlying text is automatically and transparently displaced that supposedly makes it quick and easy to annotate news articles. In other tools underlying text might get obscured and you might to have move the annotation to read the underlying text. JSK also has an “Annotate This” button that enables sites owners to make annotation easier.

Personally, I am not big into annotating so won’t compare each of the competing services feature by feature. But 5 companies providing a similar service with almost no revenues(okay i-Lighter was on working partnerships last time i talked with them), doesn’t really seem to be place to innovate.

The Others:
SharedCopy - more web annotation for everyone
i-Lighter — marker and annotation makes online research easier
