A few days ago, I saw a column commenting that Liu Ren is using his influence from Donews and his sharp writing style to make either sharp criticisms or gentle promotions of various front-end web teams, groups, products, and communities. Who would have thought that there were so many "dark" stories behind these. The stories seem well-founded and are not as "twisted" as the Lu Jia Yi incident. Additionally, I also read about a "famous domestic Chinese blog being extorted due to Google AdSense." Goodness, three letters were sent, and the audacity of the event has suddenly cast a "gloomy" shadow over the free internet. This Web 2.0 spirit of participation is truly being fully realized. These phenomena have evolved to such a fluent extent - very characteristic of Web 2.0!
