OpenID Becoming a Reality

Was just trying out the free version of Highrise, a mini web based CRM from 37signals, when I found them offering me to register using an OpenID. I was really thrilled. I have heard about the idea of OpenID before, yet have never seen it in action. I thought it was just talk but would not really take off. Now 37signals, sponsors of Ruby on Rails, seem to have been taking the lead. I really do hope many others follow suit. That would help us all reduce the ID clutter we have in today's web space.
