From Six Apart news (since I'm lazy blogging this morning):

It's been less than three years since the OpenID initiative first launched, and today we can note than more than one-third of a billion identities have been enabled.

That's thanks to some amazing news today: Yahoo has announced that its nearly 250 million users will be able to start using their Yahoo identities as OpenID identities starting on January 30. (Check out the press release for more details.)

Obviously, we've been excited about OpenID from day one, even hosting a hackathon this past weekend to see what new and cool things can be built on top of the technology. But some milestones feel even more significant than just representing a new feature; This milestone is about turning the corner from an OpenID being something that you might have to an OpenID being something that your site's users probably do have. If they have an AIM name or an AOL login, if they've got a TypePad or Vox or LiveJournal or WordPress blog, and now if they've ever signed up for a Yahoo or Flickr account, then the members of your community have an OpenID to use. Yahoo's even got a simple and well-designed guide to explain OpenID to its users.

It's not just about easier site registration or the security of not sharing your password with everyone, though those are of course great benefits. This effort has been about having a new technology as a base for inventing cool new abilities around identity and authentication.

Or put more simply, we believe that you should be able to control your identity online without being tied to any one company, site, or technology. Just a few years ago, that sounded like an idealistic but impractical idea. Today, it's a reality for hundreds of millions of people. Yahoo!

While I agree that it will be even more interesting to see Yahoo! accepting OpenID, another quarter billion OpenIDs isn't something to be complaining about. :)

Awesome, see their post! OpenID commenting as a beta feature on Blogger, way to go guys! I just tried it out and as you'd expect, it works great. Also really nice to see another site first accepting OpenID instead of providing it.
