Demand OpenID! is a new service which enables you to demand OpenID login support from websites you visit everyday. It’s a simple website and bookmarklet that provides a “one click call to action” for requesting support at your favorite websites.
How does it work? After you sign in for the first time, you’ll be given a bookmarklet to add to your web browser. Later, when you visit a website that asks you to log in and you wish it had OpenID support, just click the bookmarklet to have your vote recorded on the Demand OpenID website. Take a look at the demands for OpenID on Twitter. The service is unique in that it requires a user to log in with their OpenID, and publicly displays their votes on the website. It shows that these are people who have OpenIDs, and want to use them at websites across the internet.
Get started at demand.openid.net.
