Wikipedia isn’t very reliable, because as you previously mentioned, people submit the articles. I know it’s a very efficient and quick source, but it’s better to have a good work done with reliable information. I tell you this because I’ve had very bad experiences with the info from that page. If you want or need to use the info from that source, just make sure to read it carefully and also try to backup your information with other reliable sources like Britannica Online (which is better, and has more complete and efficient articles). Besides, in most of the schools, teachers don’t accept info from Wikipedia.
