Twitter has surpassed a milestone of 10 billion Tweets .
The 9,999,999,999 th Tweet was sent by Rafaela Marques from Brazil.
However the profile of the user who sent the 10 th billion tweet is still a mystery as the user has a protected profile. Twitter had raced past Digg, LinkedIn and New York times last April .
In December 2009 Twitter recorded its 1 billionth tweet. Twitters were tweeting 5000 times a day in 2007, 300,000 in 2008 and in 2009 it has grown to 2.5 million tweets a day.
Tweets grew by more than 1400% last year to 35 million a day, Today we are seeing 50 million tweets a day. That’s an average of 600 tweets per second.
According to the above estimate the 20th billion tweet will only take about 4-5 months.
