This just in from the Pew Internet & American Life Project….As of December 2008, 11% of online American adults said they used a service like Twitter or another service that allowed them to share updates about themselves or to see the updates of others. As with many technologies, enthusiastic users have used Twitter for more than just answering the question, “What are you doing?” Twitter has been used to help organize and disseminate information during major events like the 2008 California wildfires, the recent American elections, the Mumbai massacre and even the January 2009 crash of US Airways flight 1549 into the Hudson River. 14% of users who access the internet wirelessly via a laptop, handheld or cell phone have used a service like Twitter, compared with 6% of users who go online but do not do so wirelessly.
