 \section{Experiences, evaluation}

 It can be argued that
 the backgrounds clutter the display
 visually, making the user interface more confusing,
+and may not even be helpful.
+Indeed, many aspects of the system are a compromise between
+recognizability and some other goal such as readability, rendering
+performance, or a less well-defined goal such as user comfortability.
+
+Overall, we feel that the backgrounds can greatly improve user orientation,
+enabling more efficient views to hyperstructured content, and
+therefore the benefits outweigh the costs.
+In the following, we evaluate the implications and tradeoffs 
+of different
+aspects in the use of unique backround textures.  
 
 \subsection{Overall appearance of the resulting textures}
 
-%XXX: Furthermore, because the texture appearance has no correlation

+The most important point is generating the backgrounds is that
+the texture appearance should have no correlation with any attribute 
+or content of the document 
+so that the textures of any two important files 
+are similar only by chance.
+Having any semantics encoded in the appearance of the textures
+would prohibit orthogonal structures with differing semantics
+of the same content.

 %The background textures should be be recognizable at different scales.
