I've always been an avid fan of Wikipedia. I frequent it all the time checking whatever new concepts I happen not to know about. I have just recently discovered that a simplified edition of Wikipedia also exists! The Simple English Wikipedia is an attempt to provide an simplified edition of Wikipedia that introduced concepts in simple English words that are easy to understand by students and by people whose English language skills are not strong.
In my opinion, making things easy and clear makes things more popular. Just think how popular the For Dummies computer book series has been. I believe that the Simple English Wikipedia will gain more popularity with time and might even eclipse the main edition of Wikipedia itself.
