Want to use your Yahoo! ID to tap into Arianna Huffington’s mind? How about any of the other contributors on the Huffington Post? If so, we have some good news. Starting today, you can use your Yahoo! ID to log into the Huffington Post with just a couple of clicks.

This is just one of the new features Huffington Post has enabled by tapping into our Yahoo! Open Strategy (Y!OS) platform. Y!OS is built on the idea that Yahoo! is more fun and personally relevant when we’re open to the best of the Web and when we make it easy for you to share and connect with who matters to you on Yahoo!. And in addition to letting you use your trusted Yahoo! ID on the Huffington Post, Y!OS technology is also powering two other great new features that are live today.

The first is Yahoo! Updates. Once you’ve logged into the Huffington Post with your Yahoo! ID, you’ll also be able to automatically share the comments you make there with your friends and contacts on popular products like Yahoo! Mail and Yahoo! Messenger.

The second is a new application for the Yahoo! Homepage that you can use to get a quick view into the hottest Huffington Post articles across 80 categories in a matter of seconds.

Finally, we’re also teaming up with the Huffington Post through Yahoo! News to feature and develop specialized articles, opinion pieces and reporting. Across Yahoo! we’re always looking for ways to bring you great content, whether it’s our own original reporting through our Yahoo! Newsroom Blogs, or from great sites like the Huffington Post, a leading voice in digital news.

To get started trying out these capabilities and sync up your Huffington Post and Yahoo! experiences, head over to the Huffington Post and click on the log in with Yahoo! ID button, install the new Huffington Post App on Yahoo.com or head straight to Yahoo! News.  Or better yet, try all three.

And if you run your own Web site and want to learn how to integrate with Yahoo!, check out our Yahoo! Developer Network and behind the scenes look at how Huffington Post did it. We’re excited to hear what you think.

We have good news to share with everyone who uses Yahoo! and Facebook – in the first half of 2010 we will open the door between two of the Internet’s largest online communities. You will be able to see your Facebook friends’ activities on Yahoo! and share Yahoo! content – ratings, photos, article comments, and more – directly on your Facebook stream.  We’re doing this by deeply integrating a service called Facebook Connect across Yahoo!  properties worldwide, which we announced today.

As the place where over 500 million people visit every month, Yahoo!’s goal is to bring together social experiences from across the web, and provide one place for people to access information and stay in touch with the people they care about most.

Yahoo!’s integration of Facebook Connect will provide you with richer experiences across the Yahoo! products you use every day, such as Yahoo! Mail, Yahoo! News, Yahoo! Answers and Yahoo! Sports.  In the future, you’ll be able to choose where you want to update your status message – from destinations across Yahoo! – or directly on Facebook.

We are doing this as part of our commitment to deliver more personally relevant Internet experiences, so watch for more details in the New Year!

*Editors note: As posted earlier on the Yahoo! Developer Network blog. Apologies for any inconvenience.

Open is at the core of many Yahoo! initiatives and products. Over the past two years Yahoo! has been hard at work to change how we develop products and interact with our developer community. In addition to being avid supporters of Open Source, we participated and adopted community-based specifications such as OpenID and OAuth, and were a founding member of the OpenSocial and OpenID Foundations.  As you can see, we love Open.

But Open isn’t always easy.

Whenever we (or other companies) engage in a collaborative effort with a wider community, we are faced not only with technical challenges, but with the complex reality of intellectual property law. Patents, copyright, and trademarks are not what geek dreams are made of. This is why we have actively supported the creation of the Open Web Foundation, an organization dedicated to the creation of an open, free, and community-driven environment for the development of technical specifications:

The Open Web Foundation was founded to help developer communities collaborate and share technical innovation on the web, bringing to the world of formats and protocols the same successful grassroots approaches established by the open source community. Modeled after the Apache Software Foundation and Creative Commons, the Open Web Foundation seeks to facilitate the creation and implementation of specifications with legal agreements that make such work simple, safe, and sustainable.

For the past year, the Open Web Foundation Legal Committee has been hard at work on a new legal agreement for licensing of open specifications. While Open Source software enjoys a wide range of licenses for making software freely available, specifications and standards are usually licensed under a complex set of rules and conditions. These licenses are hard to read and spread over many pages full of terms even many lawyers don’t fully understand. There was also no suitable standalone agreement available for companies and communities to use when making their work available, forcing them into long and costly legal negotiation between the contributors.

Today, the Open Web Foundation is announcing the availability of the Open Web Foundation Agreement (OWFa), a reusable and straight-forward legal document, designed to be easily adopted by a wide range of specification communities and organizations.  Specifications made available under the Open Web Foundation Agreement may include everything from small ad-hoc formats sketched out among friends to large multi-corporation collaborations that ultimately grow into internationally recognized standards with the help of formal standards- setting organizations.

But what makes this agreement even more valuable today, is a commitment by a group of leading companies and individual contributors to apply it to a growing list of specifications. Today, Yahoo! is joining Facebook, Google, Microsoft, and others in making available the following specifications under the OWFa:

* OAuth Core 1.0 Revision A
* OAuth WRAP 0.9
* Simple Web Tokens 0.9

We are also releasing the Media RSS (mRSS) specification under the Open Web Foundation Agreement. Media RSS is an RSS extension used to syndicate rich media content (instead of just text). The specification is used when providers of media content want to share that content with a third party, usually a search engine like Yahoo! Video Search. We are also in the process of transitioning the mRSS specification to the capable hands of the RSS Advisory Board for future development.

This is just the first step in what we hope will be a new path for open collaboration and innovation on the web. The best innovation happens when we let our talented engineers and product managers solve problems. This is one less thing for them to worry about.
