Tried to link to http://en.wikipedia.org/wiki/You_Ain't_Gonna_Need_It. Shows up fine in the preview but not in the actual post. Presumably because of the quote character.

Also previously had problems linking to http://java.sun.com/javase/6/docs/api/java/util/Arrays.html#sort(T[], java.util.Comparator)
