The folks at Vovici have an interesting series of whitepapers on the use of surveys - and how to use them to build customer community. I found 'Survey Rating Scale Best Practices' particularly useful.

We are devout believers in the data driven market credo; 'why guess when you can know?' This means we keep a weather eye open for case studies and research that will move the decisions we make with our clients from the gut to the head (with or without blinking ;-).
