In June at #e2conf (tag name for Enterprise 2.0 Conference), Microsoft unveiled a new Microsoft mini-site dedicated to enterprise social computing, powered by Office SharePoint 2007.  It’s running on the sharepoint.microsoft.com environment that hosts the primary SharePoint marketing site.  On this social site, you will find content about using the social power of SharePoint to help your organization to collaborate and communicate.  Plus, the site has a fresh new design and uses the blog feature that is built into SharePoint.
