Steve Gillmor has a piece at eWeek about Sun's Adoption of RSS:

Sun Microsystems has always been about communities. Those communities early on in the company's existence were probably nowhere near as well connected as they are today, certainly in nowhere near the same real-time mechanism as they are today. And RSS is increasingly becoming the principal means of real-time communication.

If you look now all across Sun and our developer properties, you're seeing RSS feeds--little blogs and wikis--popping up everywhere. That to me is more representative of what needs to be our mainstream strategy rather than the work of a few creative individuals who want to have our big admin portal picked up by people who care about Solaris system administration.
