We recently divulged the weighting scheme we use for ranking books. Now it's time to show you how we do it for our UX topics (to see these in action, look at the topic index or any specific topic page).

Again, it's quite simple. We weight our quantitative measures for topic performance on a 100-point scale:

• Nominations from UX Zeitgeist participants: 25 points
• Number of mentions in other books: 15 points
• Web search count: 15 points
• Number of mentions in the blogosphere: 20 points
• Number of mentions in our collection of seven UX-related publications: 20 points
• Number of mentions in podcasts: 5 points

Any questions? Would you weight these differently?
