Google has announced Google Friend Connect, and Facebook has announced Facebook Connect. Both services seek to solve the Single Sign On problem. Since OpenID was created to solve this issue, will it fail against the twin heavyweights of Facebook and Google?
Don't declare it dead yet. SSO is certainly a good thing and OpenID seems to be an independent format (compared to Facebook and Google) yet it's not really seamless yet (cough Yahoo OpenID cough)
It's interesting to see if SSO succeeds and if yes, which provider, but it's the usual chicken-egg Problem: We need more high profile sites using it, and even if they do, big companies seem to be very reluctant to participate in anything that loosens their "control" over the community. After all, your personal data is valuable for marketing purposes.
OpenID is too vague for most users - "where to I sign up? "Well here, here, here, here ..."
Having a recognisable brand push this for the mass of Internet users is going to accelerate adoption. People already trust Google and Facebook with large quantities of personal info (and have a username and password), this is just a natural easy extension for them to grasp.
OpenID hasn't failed yet, but things don't look great!
I think that we as developers should support open standards and solutions so even though OpenID usability is far from being seamless it's still the best we have for now. Besides, trusting so much personal info to some company really scares me...
Here's some more discussion on this topic.
I think that OpenId will take off without people knowing that they are using OpenId.
I like sites that have a big "Sign in with Yahoo" or "Sign in with Google" button makes it easier for the average joe to get into a site. He already knows his Google password, so signing in is easy.
The widget from rpxnow.com is the best example of this.
Regardless of the players involved, OpenID is the future. It may not end up being OpenID's solution but the concept is the future of the internet. I personally prefer to call it my virtual identity. It will effectively replace email as an identifier to sites and will be what you give to people on business cards or at parties instead of an email address (similar to how people have used myspace screennames). It will be the portal through which everyone/anyone can refer to everything/anything you allow to be published to the world.
What I know is that Google Account can be used as an OpenID. It's just one type of OpenID.
Obviously what you are referring to is the OpenID account used as an OpenID. It would be early to say, btw I use Google Account as my OpenID, and creating a new ID (even OpenID :)) is boring.
Thats my opinion. What do others say?
