In the spirit of SharePoint-focused resource centers hosted on various blog sites, like Lamont Harrington's SharePoint Products & Technologies Resource Center, which, during its time, provided invaluable resources around SharePoint Portal Server 2003 and Windows SharePoint Services v2.0, the SharePoint Platform Practice of Distributed Logic Corporation, a Microsoft partner, has created an excellent collection of resources around Office SharePoint Server 2007 and Windows SharePoint Services v3.0.  This collection includes links to whitepapers, sample applications, videos, screencasts, etc that spans multiple audiences, including Architects, Managers, Administrators, and general users.  This is a great resource for folks wanting to learn more about how the 2007 edition of SharePoint Products & Technologies can enable the creation of robust and extensible business applications leveraging best-in-breed capabilities of a unified application platform.
