Most school libraries already have filters on incoming Internet access due to the Children's Internet Protection Act (CIPA). Opponents of the bill point out that the language of the bill would extend such filtering to include websites based on specific technologies rather than specific content, including websites based on those technologies that are used for educational purposes. Some educators have incorporated blogs and Wikis into classroom lessons for students due to their usefulness as a critiquing and editing tool for students' work and as a forum for comments and suggestions by teachers and other students. These educators also favor such technologies because they enable discussion outside of the classroom that can involve students and teachers as well as parents.
