Speakout Advanced p 77. Happy Birthday Twitter. Extra Listening

Happy Birthday, Twitter! The wildly popular microblogging service has come a long way since co-founder Jack Dorsey first tweeted, "just setting up my twttr," back on March 21, 2006. How far? It took more than 38 months to reach 1 million tweets. Now, Twitter has millions of users. The huge volume of "what I had for breakfast" updates and banal observations from the likes of Ashton Kutcher and Britney Spears make Twitter an easy target. But Twitter has also been a communications hub for anti-government uprisings in Iran and Egypt. And by some accounts, the company now has a market value of nearly $10 billion. Oh, and it welcomed the "winning" Charlie Sheen to its user ranks.
