Web 2.0 as compared to 1.0 is much more interactive than before. Rather than looking up and receiving information, people can now communicate with each other about the information. There are more ways to interact with the information you receive by posing questions and possible reviews based on real human experience. People are able to view the information from other people's experiences and use that to make decisions. I have personally researched products I have bought online on many different sites. I usually do a lot of research on different sites before purchasing anything online. I always read almost every review of a product I want that way I can get a feel for the reliability of the reviews. I have heard sometimes the company writes fake reviews to sell their products so I am always careful for that.
