I have never filled out a product survey.  Until today.  Let’s look at why this one is so good:

This survey is:

• Short.  From just a glance I can tell I am 1 click away from finishing the survey.  The start of a survey of unknown length that scrolls off the page is far less inviting.
• Relevant to my life.  How quickly games appear in the mail is something I actually care about.
• Showing interest.  It says “Hey, did you get that game we sent you?” rather than a less personal “Rate our service on a scale of 1 to 10.”

In addition to my being pleased with it, I’m sure GameFly gets useful data from these.
