Most of the Web 2.0 was dominated by Yahoo and I am not sure why was it so. Yahoo! may have just launched the Context Ads system – Panama, but they have some interesting web properties like Answers and Review/Rating [R/R] platform for the following

  • Y! News and
  • Yahoo! Local with Maps integration and Yahoo! Travel
  • Yahoo! Shopping and
  • Yahoo! Games and Talent Shows.

Yahoo’s R/R platform spans across 5 continents with close to 5,000 requests a second and 50 Million rated objects with 200 Million ratings. This data is also used by recommendation engine, reputation modeling and review quality. The Review and Rating platform is usable by others through APIs.
