Pete Cashmore wrote this article posing that question as well as, “does social media change the way we act?” and “does it make us nicer to one another?”
The comments at the end of the article are mixed. I for one, do not think that social media makes me a better person. Maybe a person with more access to contributing my thoughts and opinions or a person with more public visibility or a person who is more careful of what I choose to throw around online, but not a better person. I’m not sure you can say “social media makes you a better person,” or “social media makes you a worse person,” as I think that all really depends on how you choose to utilize social media.
What do you think?

I don’t think that social media, in and of itself, makes anyone a better person. However, it can, as Cashmore points out, spark “very public discussion of incidents that may otherwise have stayed under the public’s radar.” In this way, social media can play a very important role. It isn’t uncommon today for public figures to be brought to their knees by a cell phone video someone posts online of their less-than-flattering public behavior. In a way, this is a positive thing. It is much harder for a public figure to sweep an incident under the rug if an audience of millions is watching it online all day long. So while social media may not have the power to change the way an individual truly is, it can make that person more accountable for his or her actions.
