 Per Wikipedia:LEAD#Length, the introduction seems a bit too short.  It should probably be expanded from one to two paragraphs.  
 Several references have unnecessary spaces between the punctuation and the opening square bracket.
 Multiple adjacent references should be put in order of ascending reference number
 Why are teletype () tags wrapped around some refs but not others.  I don't recall ever seeing this done.  These should probably be removed to give the in-line superscripted citations a more uniform look and feel.
