Twitter announced new milestone, 200 million daily tweets

In 2008, that figure was 500,000, in 2009 it was 2 million and in 2010 the number was 65 million.

Says the micro-blogging company:

For perspective, every day, the world writes the equivalent of a 10 million-page book in Tweets or 8,163 copies of Leo Tolstoy’s War and Peace. Reading this much text would take more than 31 years and stacking this many copies of War and Peace would reach the height of about 1,470 feet, nearly the ground-to-roof height of Taiwan’s Taipei 101, the second tallest building in the world.

Twitter also posted the top "Trending Topics" for the first 6 months of 2011 which included AH1N1, Egyptian President Mubarak, Rebecca Black and the infamous Charlie Sheen.
