BrowserID

With BrowserID, there is a better way to sign in. BrowserID implements the /verified email protocol/, which offers a streamlined user experience. A user can prove their ownership of an email address with fewer confirmation messages and without site-specific passwords.

I’m all in favor of having less passwords. Plus, this also means if the site gets hacked, they don’t get any of my credentials. I don’t exactly get BrowserID, yet. Until I can use it widespread, I use OpenID whenever I can.
