One of the more interesting aspects to me about Web 2.0 is the increase use of Social Networking Sites. SNS's have led to a huge increase in user-generated content on a daily basis. Therefore, leading to a huge need for people to be more information literate than ever before in order to be able to sift through useless information to find the more accurate and authoritative information. In that sense, librarians and educators need to more than ever be seen as key professionals in advancing our understanding of information literacy and retrieval.
