The social web is a new world of unpaid media created by individuals or enterprises on the Web. These new strategies, which have the ability to change public opinion every hour-if not every minute include:
Blogs are online journals where people can post ideas, images, and links to other web pages or sites.
Social networks are places where people with common interest or concern come together to meet people with similar interests, express themselves, and vent. In addition to the examples I have already provited, there’s iVillage, Xanga, Stumbleupon, MedNetwork, and Flickr.
