How often do you use Wikipedia?  If you do a google search to define a word you will find Wikipedia as on of the top answers.  You may never contribute to the definitions in Wikipedia but sooner or later you will be reading an answer there.  Wikipedia has become larger that anyone imagined it could.  Is that a good thing or should we be suspect.  Are the definitions and background information always correct or have the definitions been sanitized?  The best way to use Wikipedia is to use it as one of the sources of information and don’t depend solely on it as your only reference.  Luke Weil will tell you that Wikipedia is the gospel.
