Your point still has some validity, but don't cheat. Do it right—in text it should be xy with italic symbols.  A serif font would make it look better; I don't know if there's an acceptable way to do that in Wikipedia articles.  The disparity in size often makes the Tex math look weird when written inline (the bottom of your E letters descending below the line is real ugly).  18:48, 6 Jan 2005 (UTC)
