Twitter Communications Director Matt Graves writes: 

It's been an exciting morning at Twitter HQ. Russian President Dimitry Medvedev just visited to meet our co-founders, Ev Williams and Biz Stone, launch two official Twitter accounts for the Kremlin (@kremlinrussia in Russian, and @kremlinrussia_e in English), and send his inaugural Tweets.

The English account appears to be a direct translation of the Russian one. 

The twitter feeds adds to the tech-savvy president's already formidable online presence, including a vlog and a livejournal account.  After only five tweets (Example: "San Francisco is a very beautiful city. Heading to Silicon Valley today to visit Apple, Yandex and Cisco.") Medvedev already 7,842 followers on the English account and 10,201 on the Russian one. 

Barack Obama, with whom Medvedev will meet in Washington this week, has already welcomed Medvedev to the twittersphere. Is it too late to start calling it the "retweet button"?
