John is strength in simplicity. The name's popularity falls further each year, but it's actually a good match for current tastes. Parents tempted by the vigorous burst of names like Trace and Colt might want to reconsider the classic, which achieves the same force without trying so hard. And parents lured by the stylish Jack can go the traditional route, conferring John with the nickname Jack, a la JFK.
