The Pew Internet & American Life Project has redesigned their website. This organization has been a valuable source of information about the Internet and how people are using it.
As an example, here are some of their recent research reports:
Twitter and status updating: “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.”
Adults and Social Network Websites: “The share of adult internet users who have a profile on an online social network site has more than quadrupled in the past four years — from 8% in 2005 to 35% at the end of 2008.”
When Technology Fails: “Half (48%) of tech users need help from others in getting new devices and services to work, and many experience tech outages when there is a glitch with their home internet connection, computer, or cell phone.”
