No new content (sorry), but I at least made a landing spot for it. There is now an "Extending Visual Studio" section on the Visual Studio Developer Center -- the future home for content on Add-ins, Macros and VSIP. Bit of content there now, but you may (should) have seen it already. http://msdn.microsoft.com/vstudio/using/building/addin/default.aspx
