I am willing to test the idea of a statistical analysis module for the 
logvalidator [1], and wonder if anyone would be interested to work with 
me on this.

[1] http://www.w3.org/QA/Tools/LogValidator/

This might not exactly perform the large-scale study that Karl is 
thinking of, but it could be a start.

I am thinking at the moment of making this module provide:
- a rapid summary of element usage over a list of documents
- list the n most popular documents without a "real" title ("Welcome to 
GoLive" does not qualify ;)
- ratio of empty versus filled alt attributes

Someone recently gave me the idea that the ratio of words over markup 
is a decent metric for either the "richness" of the page or (if low), a 
good indicator or a badly written site. Given that an image is worth a 
thousand words, I assume our formula would be something like 
(number_of_words+(number_images*1000)) / (number_html_elements).

Implementation-wise, does anyone have a recommendation on the library 
to use?

Please drop me a line if you wish to participate in this development.
