Armando Galarraga

With yesterday's blown call ending Armando Galarraga's quest for baseball immortality - the perfect game - should the human element in baseball finally come to an end with the full induction of instant replay?

Should umpire Jim Joyce's call be reversed by commissioner Bud Selig?  And how would such a ruling affect previous blown calls?

Many complain that the game is too slow already.  With constant breaks to review plays and coaches challenging calls (much like the NFL), will the game become painfully slow?

What's the popular opinion?
