Esther Dyson says that small businesses have a higher surface to volume ratio than large businesses. What she means is that small businesses are much more dependent on interacting with the outside world than large business are. Does this mean that small businesses will disproportionately benefit from Web services and easier integration? I think that's just another way of looking at what's happening to large businesses as they outsource more and more of their support structure. They're becoming "smaller" and increasing their surface to volume ratio. There's a tie-in to what Tom Malone was saying at Supernova last week.
