I think OpenID is an awesome idea, but I don't see that many sites which have it. I tried implementing it on my own site (http://www.lessonist.com/users/loginopenid). Initially I thought it was gonna take some time to learn, but it was actually a piece of cake to make and took me only 1 day to have OpenID login/registration working. I think OpenID is an awesome invention, so why not many people actually put it on their sites? Also - have you every tried implementing facebook login/registration? Is it easy?
I feel the same way too. Why in hell don't people use it? They use facebook connect when facebook connect is already included in openid plus EXTRAs. Please can people contribute to this thread. Lets solve this issue here. What is bad in something that is just so good. It's like people don't like anything that is just too good.
