Noticed a nicely-designed element on the Get Satisfaction signup form today.

While creating a new profile, Get Satisfaction asks you if you happen to belong to one of a few sites that serve up hCards. (they may be using an API as well) If you do belong to one of the sites, simply enter your username and getsatisfaction will pull down your hCard and pre-populate your new profile with the information. Nice and simple.

They’ve done several things well with the design, which I’ve annotated in Skitch…

Very nice interface element. Well done!

Know of any other well-executed identity-related interface elements?
