We'll post these as they come, but this presentation by Disney VP Mike Pusateri and his associates, about his company's use of wiki, blog, and RSS reader technology at a O'Reilly conference offers strong pointers to why enterprises should consider RSS now.
Mike is responsible for about 800 desktops at Disney. Is RSS a department-level pheneomenon right now? How about Microsoft's 1,000 bloggers?
