A well-known example of such a program is Wikipedia, the free-content encyclopedia. With 13,000 active contributors working on more than 1,800,000 articles in over 100 languages, Wikipedia is truly a user-input system that results from international collaboration. The downside, however, is that newer articles are often not as well-balanced and comprehensive as the more mature ones; fledgling articles tend to be full of misinformation and vandalism (“Wikipedia”). Users simply need to use good judgment to determine whether what they read can be taken for face value. With time, the system will become more accurate faster, thereby improving the integrity of its articles.
