Zoo.com: A Safe Search Engine for Kids

Zoo.com claims to be a relatively safe search engine that allows users to find content from sources like Google, Wikipedia, ABC News, Fox, and Yahoo. It has specifically designed a filtering system for children, which includes no image search and blocking common terms associated with adult content. For example, you can search for "breast cancer" (breast cancer) but not directly for "breast" (breast). The purpose of Zoo.com is to allow parents to avoid having to monitor their children's searches in detail (via software or hardware).
