One of the challenges many face with OpenID is the process by which you convert an OpenID URL into a local username or identifier of some kind. This process is essential for services that want to offer friendly URLs to a user's profile on their service (e.g. http://twitter.com/byrnereese). However, if a user uses OpenID to login and/or register then you create additional overhead somewhere in the process for a user to select a local identifier on the service because by default all the service has is some cumbersome URL to unique identify the user.
Enter Rejaw. I can't remark on the service itself because all I have done is register. But it is its registration process that I so far appreciate the most. No where in it did I need to enter in a password or a lot of profile data. Bravo. But not only that, Rejaw incorporated into its registration flow the selection of a local username. Major props.
Here was the basic flow as I experienced it:
Click "Sign-up for a free account," and then click "Use an OpenID"
Authenticate using your OpenID.
Select your username and enter an email address.
Confirm your email address.
Find your friends.
