Twitter has launched a video to mark the occasion:
When I published my very first tweet 22 November 2007 (thanks My First Tweet), I apparently felt like a late adopter to the twittersphere. In retrospect I don’t think I was that late though, the service’s growth considered.
It took 18 months before Twitter grew to 500Â 000 accounts. Today 500Â 000 new accounts are created and users publish more than 140 million tweets a day. According to the blog NRKbeta Twitter’s considered the world’s 9th website today. In Norway 7Â % of web users use Twitter every week or more.
