I just posted a comment on a sad, but heart-felt post, footsteps, and livejournal asked me to authenticate. I selected OpenID and used my Technorati Profile. One click later on my "Authenticate your Identity" page and my comment had posted. You see, Technorati is an identity provider so every Technorati member has an open id.
Pretty cool. Amazingly simple.
