The mediator then loads the page and adds in any annotations stored in the annotation server. Annotations can be added at any point in the document which makes it very easy to produce idea-level commenting on any Web page. Though this level of precision is very desirable, the implementation of it is a bit clumsy. The lines of the document that one wishes to annotate must be retyped into the commenting window. A different implementation would add much to the usability of the system.
Integrated annotations appear as small arrows that surround the text that is annotated.
These arrows act as links to the actual comment. Document annotations simply place the comment at the bottom of the document. The presentation of comments is not entirely intuitive. In order to annotate an already existing annotation, one can annotate the comment page just like any other Web page. This allows for a hierarchy of annotations but because of the nature, it is easy to get lost in the replies to comments.
