In July 2011 Yandex reported that Russian-speaking audience of Twitter crossed 1 million mark. Today Yandex’s Twitter user rating includes 1,68 million accounts. This is over 50% growth in the last 6 month!
Vedomosti.ru, one of the major Russian newspapers, writes that a lot of this growth happened during Russian Parliament elections time in December 2011 and that some of Cyrillic terms such as “выборы” (elections), “Путин” (Putin) made it into worldwide trending topics. Many argue though that thousands of Twitter accounts were created during- and after-elections period to tone down the protests, which might have contribute into the growth figure.
