At my recent talk I pointed folks to my FURL site for links to all the tools I discussed. I've just received a note from a school librarian saying the filter will not allow access to that site. That is so wrong. Is Google or Yahoo filtered? FURL and Delicious and Technoriti and the rest are another method of finding information on the Web. Why can't a teacher or librarian bypass the filter? Commercial filtering programs also have hidden biases. A better option would be to go with an open source product like DansGuardian.
