On Monday, Kevin Weil, member of the analytics team at Twitter, blogged that the social networking site, Twitter is fielding 50 million Tweets every day.

People are tweeting around 600 tweets per second, on an average.

In year 2007, Twitter posts accounted to only 5,000 tweets per day. The number elevated to 300,000 in 2008 and 2.5 million in 2009. Last year, the average number of tweets rose 1,400% to 35 million every day.

The numbers do not include Tweets from accounts identified as spam.

The micro-blogging giant, who usually prefers to remain silent about their statistics, disclosed the numbers on Monday.

Weil said that tweet deliveries are a much higher number because once created, tweets must be delivered to multiple followers. So tweets per day is just a start, we will have more to share when we have additional information, he added.

However, the total number of Twitter users is unknown to the public, which has been kept as an internal statistic at the company.

With this remarkable achievement, Twitter is sure to give other networking sites a tough competition.
