There's an old saying, ”Great minds think alike.” Or is that just what we tell ourselves when we find people who think as we do? Sean Parker, William Galston and Joe Trippi conclude their dynamic discussion on civic engagement and the Internet. This time they answer the question: Is the Internet a divider or a “uniter?”

Bill Galston of the Brookings Institution says that the Internet has added to the polarizing of our political and civic mindset, creating niches of like–minded people. While Galston supports his argument by citing a recent study conducted by the Brookings Institution, he does acknowledge that in some cases having like–minded people come together online may indeed be constructive.

Sean Parker aptly defends online communication. While admitting its origins as a somewhat frivolous social application, Parker says the Internet and social networks in particular are reaching a level of maturity by providing users with meaningful ways to engage in political and civic causes.
