Twitter numbers explode

SAN FRANCISCOO, CA - Twitter has seen a huge increase in activity over the last year. The social media site announced on their blog that their users post 200 million tweets a day. That's a dramatic increase from 65 million a day last year.

These numbers seem huge, but look bigger when you compare them to works of literature. Assuming the average tweet is 25 words, that means that "every day, the world writes the equivalent of a 10 million-page book" -- or 8,163 copies of Leo Tolstoy's epic novel "War and Peace."

Twitter's international reach is reflected in its top trending news topics for the first half of 2011. Among them: Egypt's revolution, the fighting in Libya, the crippled Fukushima nuclear power plant in Japan and the British royal wedding of Prince William and Kate Middleton.

Twitter did not say if its users are tweeting more often or whether the surge in tweets is simply just a reflection of more people signing up.

Twitter is estimated to have more than 200 million users. In a post celebrating its fifth birthday in March, Twitter said that close to 500,000 new accounts are created every day.
