Not just that. I think social media is destroying democracy.
Things like Facebook, they provide what I like to call opinion enclosureism. Where healthy public discourse and discussions are made up of positive and opposing viewpoints to be considered, Facebook allows mostly for either a 'Like' and positive response, and it's easy as heck for the user to simply delete any viewpoints that disagree with the user, or remove the person from friends list so that the user will never need to hear from him/her ever again.
This is directly opposite to Socrates, when he preferred to spend double the time to research and consider his opposition's point of view instead of focusing on his own case. Facebook isn't helping with general intellectual development, and Twitter even more so when it allows shallow, unthinking people to think that 140 characters is enough to express a full-bodied, nuanced opinion.
