Yandex AnswersSeems like innovation is diminishing at least on some level, since now the Russian search giant Yandex has launched their own Q&A service. Yandex Answers is similar to many of its rivals in the western world, like Yahoo Answers. Yandex Answers is not alone however – Google has its own service as does Mail.ru.

Yandex Answers has an added value to the service however. It has readily indexed more than 4.5 million questions and 14.4 million answers from various blogs and forums. This should give it a head start compared to its rivals. On top of these, the regular Yandex member can answer the questions as an expert on the topic. Currently the only visible business model on the site is advertising.
