"Nobody really knows what it means... If Web 2.0 for you is blogs and wikis, then that is people to people. But that was what the Web was supposed to be all along... Web 2.0, for some people, it means moving some of the thinking the client side, so making it more immediate, but the idea of the Web as interaction between people is really what the Web is. That was what it was designed to be... a collaborative space where people can interact." Other critics labeled Web 2.0 "a second bubble" (referring to the Dot-com bubble of 1997–2000), suggesting that too many Web 2.0 companies attempt to develop the same product with a lack of business models. For example, "The Economist" has dubbed the mid- to late-2000s focus on Web companies as "Bubble 2.0".
