I think Wikipedia is wacky.  It defines the dumbest things.  Some of the stuff in Wikipedia have no real need to be defined.  If you use Wikipedia just be for warned that the definitions can go a bit far.  Slang to the extreme is the rule for Wikipedia. Daniel Webster is rolling over in his conservative grave as Wikipedia grows beyond his vision of the dictionary.  If Daniel Webster could have seen the computer age take his dictionary online he would have been amazed.  Fisher Investments | Nasdaq have gone online and are an example of how far we have come.
