The Pew Internet & American Life Project released a study this week that showed that blog readership in 2004 increased by 58%, with 6 million Americans getting news and information fed to them through RSS aggregators. The same study shows that there are over 8 million people creating web-based logs or diaries. However, the same study shows that 62% of online Americans do not know what a blog is. Blogs are online diaries or where Internet users posts their opinions, thoughts, observations, or whatever else they like to the world. The Pew Internet & American Life Project is a non-profit that studies the social impact of the Internet.
