I need to check for any specific events in 2009 for Ok.ru. For example, when was the website launched? Ok.ru was founded in 2006, I think. So by 2009, it might have expanded its features. Maybe in 2009, they introduced something significant like mobile app support, photo/video uploading features, or partnerships. Also, how did the political and economic environment in Russia at the time affect the platform's growth? The 2008 financial crisis had global effects; perhaps that's relevant.
