Using Microformats to simplify registration forms

GetSatisfaction.com is a community website that encourages conversation between consumers and companies.

Their registration form is a clever, real-world example of how microformats can make life easier on the web.

If you’ve already registered with flickr.com, technorati.com, twitter.com, or any of several other sites, you can enter your id for that website off to the right of the form and it will pre-populate the GetSatisfaction form with publically available information. Specifically, it uses the hCard microformat to extract the public portions of your profile on those other websites. The hCard microformat allows for individual elements of your contact information to be parsed and used.

If you haven’t already, go try out the form at GetSatisfaction and see it in action.

I’ll build a live example of this approach here in the coming weeks and post the code.
