Need more java: Call to Sun bloggers

I am  subscribed to the sun blogs from Sun Microsystems as well as MSDN blogs from Microsoft. The MSDN blogs always have good content each and everyday on the new technologies and good useful information and code snippets on the development on the Microsoft.NET platform. But i rarely see any good content on Java in the Sun blogs. I really don't understand why the blogosphere is not used by Sun compared to how much Microsoft is using it in the MSDN blogs.
I know there are good communities providing lot of info on development on Java but i do feel more blogging on Java by the people implementing new features and version will give it a big boost. Sun you need to take a note on this from Microsoft.
