Thought this signup form from Kickstarter was rather well done – presenting the signup form in its entirety on the same page as the login form; they obviously know that a large number of users each day are new to the service so give them as few opportunities as possible to fall by the wayside. Interesting how services like Twitter and Facebook are becoming standards for authentication; it’s as though OpenID has finally come of age, all we needed were central services with sufficient reach to act as the broker of your credentials. When I first signed up to Stackoverflow back at the start of the public beta, there were few available services I would willingly choose to trust as my provider.
Interesting how the visual focus of the page is heavily weighted toward creating a new account. I didn’t even get as far as reading the Facebook option before I started typing. I wonder if that’s intentional.
