Marketing 2.0 ist a kind of product development, where the product quality, distribution, brand, and other aspects are not viewed as the sole responsibility of the brand owner. Somehow, the brand has been considered as belongs to the community. Promotion is not in the form of communication, but instead in the form of conversations. And product quality is also considered as the responsibility of the consumers. It makes sense! The consumers have some objectives to improve the value of their lives, and therefore require support from the environment, including various commercial products, thus we as consumers have the interest to make those products well managed, developped, and grow better.
