Gmail User Happiness Survey

Remember people, I did a post on the Orkut User Happiness Survey. Gmail today is out with their own version of the Happiness Survey, shockingly titled,the Google Mail User Happiness Survey. Here's a screenshot.
Click to enlarge. The survey link is available in your own inboxes just left to the Mail Settings link, or go to this link.
Google has been publicising their goodwill and real ethical side, firstly with Adsense click space reduction and now with User Happiness Surveys. I am sure if they read my post on the 5 Gmail wishes, they'd surely get some answers. What say Larry,Sergey?
