A while ago, I came across a unique registration form built by Jeremy Keith for his audio sharing site, Huffduffer. Though it asked people the same questions found in typical sign-up forms, the Huffduffer registration form did so in a narrative format. It presented input fields to people as blanks within sentences (Mad Libs-style, if you will).

There’s even some A/B testing information to lend some weight.
I know I posted a link to this article on Twitter yesterday, but I thought it was such a clever and simple idea that I wanted to make a note of it here.

Wow great idea. I can see why it would improve response – makes the form form personal.
Hmmn lovely…and puts the person in control and in conversation. By the way, your blog Geoff is wondrously interesting…have been here for half-an-hour when am supposed to be doing something for work deadline. It’s unpredictable, quirky and erudite – fab!
Thank you Pippa. :)
