Facebook is proving to be a bigger problem than anyone expected. A majority of reported bullying cases are coming from social media, specifically Facebook. That should say something.
The easier it is to communicate with people the easier it is to be a jackass to people. Used to be if you wanted to hang out with your friends and say bad things about celebrities the most public you’d get with it is having the discussion in a bar, maybe a dozen people hear you talk, and said celebrities never find out about it. Now you post it on your FB wall, or Twitter, or even their wall, and millions, including the target of your derision, hear it. As always the problem isn’t with the tool, it’s with the people using it.
