Yahoo’s keynote proved very interesting. In it they announced a new technology they call, Y! OS. This technology is to be the beginning of a new Open, Social Strategy for Yahoo, and with the technology, as they term it, they are “Re-wiring Yahoo”.

Starting today, Yahoo is opening up the beta for their Search Monkey platform, which is to be a new way to organize and format search results. He showed some interesting formatting of search results with reviews, descriptions, etc.

According to them, Yahoo’s open strategy is about opening up all the properties of Yahoo. First of such will be an Application platform. They will be socializing all of their properites, unifying the user profiles, and integrating the ability to add “applications” across all Yahoo properties and apply Social properties to those applications.

According to Yahoo, they are “Not creating ‘yet another social network’”. Yahoo does not view “Social” as a destination. It should be an integrated environment. He showed some examples of integration within the Yahoo mail environment, showing a way to pop up messages most relevant to the individual through the Social Graph. Taking Yahoo portable will also be an integral part of this.

Yahoo says that later this year the first version of Y! OS will be delivered. This will include the beginning of Social Graph and Application Development platform, and an entirely new dimension of developing applications at Yahoo will become available.

This is huge news for Yahoo - it puts them up at par with Google and Facebook, and will change the way you use the internet as you know it. Expect to see more from Google along these lines in the future - I believe the iGoogle OpenSocial integration predicts this. With Yahoo as a part of the OpenSocial foundation, I expect them to integrate OpenSocial as part of this, and move to a fully social strategy. I’m very excited for this announcement and look forward to Y! OS to come into play at the end of this year.

Today Yahoo announced that they are joining forces with the OpenSocial platform, and will be joining both Google and MySpace to build “The OpenSocial Foundation”. This new foundation “will seek to ensure that the technology behind OpenSocial remains implementable by all, freely and without restriction, in perpetuity.” It is modeled after the current industry-supported OpenID foundation. As an addition to that announcement, Google has released “opensocial.org” to promote the development of OpenSocial on a standard platform away from the Google environment.
