You may have noticed that our books are ranked (if not, have a look at the UX Zeitgeist book index). We believe our ranking system is wildly, brilliantly innovative and one of the most useful features of UX Zeitgeist. But our staff chaplain, Father Rosenfeld, has encouraged us toward walking a more generous, altruistic path. So we're divulging the recipe for our book ranking secret sauce here.

Truly, it's quite simple. We weight our quantitative measures of book performance on a 100-point scale:

• Nominations from UX Zeitgeist participants: 20 points
• Number of mentions in the blogosphere: 15 points
• Amazon sales rank: 20 points
• Number of mentions in our collection of seven UX-related publications: 15 points
• Number of LibraryThing collections that include this book: 15 points
• How LibraryThing members rated this book: 10 points
• Number of mentions in podcasts: 5 points

Does this sound like a reasonable approach? We want UX Zeitgeist to be a community resource, so we're completely open to other ideas. Lay'em on...
