Twitter turns three today and in that short amount of time, it has completely transformed the way 6 million (and growing) people communicate with each other.
According Nielson, Twitter grew by 1,382% from February 2008 to February 2009.
Perhaps most interestingly, Nielson documented something that I’ve been observing for quite some time, Twitter’s largest adoption is stemming from adults, not primarily via teens or college students as you might expect. In February the largest age group on Twitter was 35-49; with nearly 3 million unique visitors, comprising almost 42 percent of the site’s audience.
