Annotations? Why?

Definitions in Wikipedia: http://en.wikipedia.org/wiki/Annotation

An annotation is metadata (e.g. a comment, explanation, presentational markup) attached to text, image, or other data. Often annotations refer to a specific part of the original data.

Uses by students: Students often highlight or underline passages in books in order to refer back to key phrases easily, or add marginalia to aid studying

Uses in source control: The "annotate" function (also known as "blame" or "praise") used in source control systems such as Team Foundation Server and Subversion determines who committed changes to the source code into the repository. (also: taging/versioning, linking to tickets)

Imaging: In the digital imaging community the term annotation is commonly used for visible metadata superimposed on an image without changing the underlying master image, such as sticky notes, virtual laser pointers, circles, arrows, and black-outs
