In just 5 years, Twitter has exploded to 200 million registered users.  And here's the truly amazing statistic: Twitter processes 350 billion tweets every day. The service launched in March of 2006, but moved out of private beta in July.  Who was the first indie music musician to get actively involved on Twitter?  We're pretty sure it's avant cellist Zoe Keating. She was there from very beginning and now 1,327,547 follow @zoecello - a number that exceeds many platinum selling artists. Check out the Twitters Stats Chart & Timeline:
