Brent Sleeper: Why web services matter (the quick version). “Web services will do to the underlying two tiers (data and logic) what the web did to the presentation layer… In applications like the UserLand’s Radio content management software and Radio Community Server collaboration environment, by contrast, we’re already seeing early examples of systems being designed with their business logic and data storage distributed and shared by a cloud of nodes. Radio is neither completely centralized nor completely stand-alone. It’s a pointer to how other sorts of applications will begin to look.”
