A few semesters ago I had a course of History of Civilization. This course, as we know, require students so much materials to read, using books, and other sources. However, before midterm exam, we were provided with main questions that we should answer on the exam. Lots of questions, and no books on the hand. I started searching information about historical facts and persons, typing the same in the google search. What I had found was very interesting: all the links on the first page of search results were to wikipedia.org. I had found all my materials on this site. Easiest way I thought. I learnt all the things and went to the exam. However, results were not so good. So, was it my fault, or wikipedia's? It was question that i wanted to answer. Maybe, it was my fault, because i did not like this course at all.
After all, I use Wiki everytime i wanted to find some historical, even modern events information. If i have some misunderstandable things, i try to find it in WIKI. And I can find everything i want in 90 percents. I think, if people whole of the world use this encyclopedia, that could provide with many informations, I should use it. And now, I rely on this encyclopedia, but I also try to check any information with the reliable books, using wiki as an additional resourse.
