Yuvi, I agree with you. Back in 2005, when I joined Wikipedia, I remember a teacher failing a classmate for submitting a physics project with Citation Needed written all over it. I was smart enough to rewrite it. I meant, use of Wikipedia for reference in everyday study. Like for example, I studied Introduction to COBOL from the Wikipedia article. Similarily, I studied my tenth standard history from Wikipedia. The textbook is my natural enemy.
