Friends who often visit Douban should have noticed that Douban has recently launched a new service called "Brand Partnership" (in English: partner). Douban is a well-known Chinese Web 2.0 site, originally starting with book reviews, music reviews, and movie reviews, and primarily earning revenue through affiliate programs with websites like Dangdang and Joyo. Starting this year, Douban has added advertisements to many of its pages, exploring new ways to monetize. Brand Partnership represents another new attempt in this direction. Douban has always been synonymous with being avant-garde; its choice of Python as the development language demonstrates this, and it was also the first true Web 2.0 site in China.
