Twitter, 3 Years Old

Happy Birthday Twitter, you are 3 years old now and still online. It all started on 21st of March 2006 when Jack Dorsey sent his first Tweet and, together with Evan Williams, Biz Stone and others, created a social media company that has grown over 1300% in the last year.

According to a post on Nielsen Wire, unique visitors to Twitter.com increased 1,382 percent year over year, from 475,000 unique visitors in February 2008 to 7 million in February 2009. This growth earned it the title of “fastest growing member community site,” a term that encompasses not just social networks but any online community – even one such as online wiki community Wikia, which, incidentally, came in at number five on the list. Zimbio and Facebook followed Twitter, growing 240 percent and 228 percent, respectively.
