Twitter Closes In on 10B Tweets Total posts up from 1B a year ago, 5B just 4 months ago By Harry Kimball, Newser Staff Posted Mar 3, 2010 10:26 AM CST 1 comment Comments A Twitter user. (AP Photo) (Newser) – Twitter isn’t growing as explosively as it used to, but the volume of traffic on the microblogging site is still expanding fast enough that it should hit 10 billion total tweets in the coming days. That’s up from a billion about a year ago, and 5 billion just 4 months ago. Gauging the progress is quite simple, Mashable reports; just look at the number tag at the end of a tweet’s URL. A recent one read 9917803012, and the site produces about 50 million a day.
