The neat use-case I see coming out of this is enhancing an onboarding process.<p>I work for a company which sells wine online, and a large number of people have strong preferences about the types of wines they like (red, white, chardonnay, half-cases, etc.)<p>It's useful to give people a survey - combined with an explanation of how the site works - as they are signing up. Even more useful is to use their answers to show the new customer a wine which is suited to their tastes. (If you like high-end reds, it wouldn't make sense to show you a half-case of inexpensive white wine to convince you to make you first purchase.)<p>And if our marketing department can manage their survey, marketing copy, and graphic design without having to ask developers every time they want a change (or if they can save me the time of writing a customizable interface) then all the better.<p>Onboarding. That's where it's at, yo.<p>The idea of surveys as a paywall mechanism (eg, New York Times paywall with a survey) is, at first glance, pretty unappealing, because paywalls are de-facto abhorrent. But we'll see; I may not mind filling out a 4-question questionnaire in order to read an article that would otherwise be blocked. Especially if I know that after filling it out once, I will never ever have to fill the survey out again.<p>And let's not forget about the adult industry! Instead of captchas... well, why not get some interesting marketing analytics out of the deal?<p>Interested to see how this evolves!
