what is Social Media doing to us?

The Opinion Pageant:

The rise of social media as the primary mode of interaction has caused us to overvalue opinions as a gauge of character. We are now defined more by what we say than what we actually do, and words, unlike deeds, are cheap and easy to counterfeit.

"Unlike the open source movement or Wikipedia, participants of social networks do not seem to follow a common noble goal, or celebrate a community spirit. The focus here lies on the individual." (Dennis Knopf)
