Knowledge Network as Technology Preview (Social Networking ;-)

"We are announcing a change to the distribution and support model for KN. Our new plan is to release KN as a Technical Preview rather than as a supported product feature of Microsoft Office SharePoint Server 2007. As a Technical Preview, KN will still be available to customers as a web download at no additional cost and will include documentation and community support. However, Technical Previews are not supported or covered by standard product support services or warranties. We appreciate all the enthusiasm and interest in KN from so many of you. We’ve also heard feedback that KN should be integrated into the core Office Client and Server products rather than distributed as a separate component. Responding to this feedback, Microsoft has decided to distribute KN as a Technology Preview in this release and to review the KN feature set for inclusion in future releases of the Office system.

We’ll provide more information soon about the Technical Preview plans for KN. Our plan is release the Technical Preview version of KN in the first half of calendar year 2007."
