The micro-blogging service said that number of daily messages sent jumped from 5000 'tweets' in 2007, 300,000 in 2008, and 2.5 million in 2009.
Tweets grew 1,400 percent last year to 35 million per day, Weil said. Today, we are seeing 50 million tweets per day -- that's an average of 600 tweets per second, Kevin Weil, a member of Twitter's analytics team,.
The 50-million figure does not include messages from accounts identified as spam, Weil said.
