There's a spirited discussion going on at another place I post about a recent deadspin.com item. (I won't link to it, since the title is NSFW. It begins with "Let's Listen To Joey Votto Scream...") The video and accompanying text showcases Joey Votto's new habit of screaming a "torrent of" a specific obscenity after at-bats that don't end in him reaching base.
I contend that it's a bad thing. It makes him look self-centered and childish, IMO. It could also drive families with kids away from the ballpark. Imagine having to explain to the 5 year-old you brought to the game what Joey just screamed 3x at the top of his lungs on the way back to the dugout!
Most posters at the other place are over the moon about it. They consider it a sign of his concern for his performance and commitment to improve.
