Twitter just announced another milestone. According to the statistics, Twitter users are sending 200 millions tweets per day. Yes, it’s bigger than some country populations like Japan, Russia, or even Brazil!

Halfway through 2011, users on Twitter are now sending 200 million Tweets per day. For context on the speed of Twitter’s growth, in January of 2009, users sent two million Tweets a day, and one year ago they posted 65 million a day. [source]

Twitter also have a visualization on the number. So, if:

• a single tweet consists of 25 words in average,
• War and Peace book has 1,225 pages and 500 words per page

Then, 24,500 tweets is equal to a single copy of War and Peace. And 200 millions tweets is  approximately equal to 8,163 copies of War and Peace book.
