Web 2.0 is changing the world because it allows people more ways to connect to others around the world. It also is allowing us to learn more about people and their cultures, so that we won’t be as ignorant about our surroundings and the world around us. Things like blogs and Wikis permit us to share our knowledge of things and learn more from others.

We also are able to express ourselves out to the world.

But Web 2.0 is not only making a reformation on the world, it is also harmful. Some people can share too much information and someone can use that info to find you or search you down. Everyone aren’t friendly, and some people are out there just to hurt you. So be careful and don’t give out too much information.
