An impressive milestone for Twitter
On Monday, Twitter celebrated its fifth birthday, proudly noting that it had come a long way since that first tweet. Biz Stone, one of Twitter’s co-founders, said in a blog post that more than 140 million messages are sent across the network each day; that’s up to 1 billion every eight days. Mr. Stone also said Twitter was adding nearly 500,000 new users each day.
To celebrate its birthday, Twitter has set up a new Web site called Discover Twitter, which tries to showcase how people have grown to use the service, including a number of well-known celebrities and government leaders.
