This is a screenshot taken from Dmitry Medvedev's Twitter page Monday May 7, 2012. Dmitry Medvedev, Russia's one-time tweeter-in-chief, was characteristically modest and a little flat when his term as president came to an end Monday: "Thanks to everyone who showed me support in four years in the post of Russian president. We'll continue our contact. There's a lot of work ahead," he tweeted an hour after Vladimir Putin was inaugurated as his replacement. It was the end of an era, the kind of moment when a Twitter buff might unleash a barrage of 140-character spurts of sentiment, humor or self-aggrandizement.  (AP Photo/Twitter)
