One of the darker aspects of the internet is the power some people claim due to their anonymity. When an individual chooses not to use their real name -- and I realize there are legitimate reasons for doing so -- some folks become very brazen and antagonistic. They write or say things that they would NEVER say to a person's face in a million years!
Take, for example, what one fan tweeted at Steve Blake, a guard with the Los Angeles Lakers professional basketball team: "I hope your family gets murdered." This comment was made because Blake missed an important shot in a game the Lakers lost.
I bet that there are few people in the world who would walk up to another person and say that to their face. In almost ANY situation I can think of, such a statement is wholly inappropriate and mean-spirited. In this particular case, we're talking about a game -- something that shouldn't be that darn important in the overall scheme of things.
But some individual decided to write such a nasty thing anyway. It is sooo very easy to do when there will be no personal backlash because of the cloak of anonymity.
