http://en.wikipedia.org/wiki/ I consult this online encyclopedia frequently; anytime I need a general overview of a topic I have little or no knowledge about. What makes this site different from other resource guides and the reason why I love it is that one does not need to be a specialist to be a contributor, so anyone can add to it. In my opinion this makes Wikipedia great because it has information about anything and everything. I have not come across a topic that I could not read about in Wikipedia. It makes me smile when I am navigating another website and they reference Wikipedia for definitions or more information. When referencing Wikipedia just make sure you consult other sources to verify the information you've gathered is actually true.
