...the worst possible data comes out of any method in which the respondants select themselves. but all respondants select themselves. wether they choose to click the website, or mail the form in or talk to the person on the phone. unless your observing from afar then the data is from those who choose to respond. In this case i would think it is the best data avaible. Its not like we can ask E-F to hand over the addresses or phone numbers of people who use poser nor could we get the e-mail addresses from renderosity or DAZ or the like.
