<link erased as it points to the wrong location> provides a suite of tools that "allow individuals to comment on and view existing hypertext documents (MeatBall:CritLink), to navigate the Web using a graphical interface (CritMap), and to archive email exchanges using the features of hypertext (CritMail)"

I've played a bit with CritLink. It is quite useful in its way.

The key capabilities CritLink I like are these:

• Nice interface for adding comments to specific paragraphs
• The comment can be put relative to a specific phrase within the paragraph.
• The "original text" is not modified, so it remains readable, and the original author has full control over the content.

This last point was a critical obstacle to adoption of TWiki where I used to work.

The CritMap tool looking promising. If TWiki had a database of links, that kind of map would be very nice. The best explanation is the paper from Hypertext98: http://www.cocoon.com/writings/contextures.pdf
