English to Chinese Tech/Engineering IT (Information Technology) Web 2.01

Web 2.0 lives on a services-based ecosystem with a richer UI, enabled by the higher prevalance of users with broadband connections. Appplications are driven by richer, more interwoven data, and include features such as friend of a friend (FOAF) and tagging.
The value proposition isn't dominated by delivering the party line of the central site management, but is more about user input and participation; in short: social networking. The web service approach, having less direct control of the final presentation, also results in the injection of less parasitic content (such as spam and pop-up, pop-over and pop-under advertising).
