An intentionally simple poll. Please: first click the button that matches your feeling then, only if you wish to know a little more about the Net Promoter Score®, follow either of the links below thank you. Please respond with a focus on one thing alone: the likelihood of you recommending Yosemite. (Not whether you would recommend it based on its levels of reliability, not whether you would recommend it based on its degrees of beauty, and so on; simply the likelihood of you making the recommendation.) Net Promoter Score® background reading Net Promoter Score (NPS) Criticisms and Best Practices (2009) Comparison of Three One-Question, Post-Task Usability Questionnaires (PDF, 2009) Personal note I waited three hours before adding my response (the twenty-third), then read the first of those two documents. Prior to that I knew nothing about NPS measurement or interpretation. I have not yet read the PDF.
