I love it. First, I can move on to another game and watch it if I'm still in the mood for baseball. Second, if I just want to watch a game, it's over before I'm bored with it. Third, the long term effect of this is that I can start taking my kids to baseball games without leaving in the sixth inning. Fourth, I can start actually letting my kids watch weekday night games.
Short baseball games are good. It's what we all grew up with, provided you're over 30 years old.
