TWITTER users are creating 50 million messages of 140 characters or less each per day, the micro-blogging service said on Monday.

Kevin Weil, a member of Twitter's analytics team, said in a blog post that Twitter users were writing 5,000 "tweets" per day in 2007, 300,000 per day in 2008 and 2.5 million per day in 2009.

"Tweets grew 1,400 per cent 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."

Weil said the 50-million figure does not include messages from accounts identified as spam.

The number of actual "tweets" delivered is far higher because many messages are delivered to multiple accounts, he added.

The San Francisco-based Twitter does not release figures on the total number of users of the service, which was launched in August 2006.
