I wanted to try the predictor about pets, since I figured that would give me an idea of how seriously I should take this, but I was greeted with a registration page. Why is an account required just to do the simplest thing?
Registration is only required to contribute data to a predictor, which makes it more accurate. Predictors need a minimum of responses before they can predict, which is indicated with the "needs responses" tag on the predictors list. I've been playing around with directing users right to the page for submitting a response when a predictor needs more responses. In your opinion, is this too confusing? For reference, the predictor page for the pets survey is: http://www.cleversurveys.com/survey/5709198289534976_5629499534213120/what-pet-should-i-get
