A lot of the comments here assume you can see truth at a glance, but intuition is fallible. I'd be rather curious to know if Huffduffer did A/B testing of this

A lot of the comments here assume you can see truth at a glance, but intuition is fallible. I'd be rather curious to know if Huffduffer did A/B testing of this form vs. a more traditional signup page. Doing that test, and gathering real data, is the surest way to know if this alternate design is any good.
