Agreed, Rob! I think on a higher level this also brings up the more general question of whether a unique, well styled UI element adds or detracts value. It is subjective and varies on a case by case basis. Perhaps a lesson to extrapolate is that taking such a risk with your primary action button can swing conversions a lot whereas taking that risk elsewhere on the page (eg Mailchimp's quirky status messages) adds personality and may help conversions without betting the house. It would be great to compile a list or visualization of successful UI quirks.
