We analyze this data to better understand how visitors use the site, so that it can be improved.
This data is strictly anonymous, and will never be resold or transferred.
Out of respect for your privacy, we do not use any third party "tracking" cookies.
We do use "web beacon" images and other techniques to discern between visits by web indexing 'bots and human viewers.
These techniques are discussed in "Web Site Measurement Hacks" by Eric T. Peterson, published by O'Reilly Media, Inc.
