Thing #13 Tags

Tags would be invaluable for research. With descriptive tags someone could save a lot of time by not going to so-so websites and find the ones best for the topic. A teacher could use tags to bookmark the best sites for students to use for a project and keep students limited to 'teacher approved' sites. Teachers and librarians could use the social tagging sites for the best tags to use for their blog, picking widely used tags instead of more obscure ones.
