Wikipedia is a wealth of knowledge.  From spelling to information about a words meaning.  To help broaden your vocabulary and help you become a more rounded and versed person.  Wikipedia is the quickest and easy way to have a full dictionary at hand always with your smart phone or computer at hand.  You can go to the library which are slowly disappearing as technology gets better and fast.  Books are becoming a lost thing also.  Book stores are also going away because of the smart phones and computer that can find a book and be sent in a snap or a blink of the eye to your unit with a click of a key and you can start learning anything you want just as fast as it was sent to you.  Mr. Kenneth Fisher is a pro at Wikipedia.
