I definitely think that Facebook plays a big role in the world today. Everything that we see influences us in some way. Since so many people spend so much time on Facebook, a lot of what we see comes to us through Facebook. This gives Facebook a lot of power to influence through it's platform. If Facebook decides to promote positive posts about a certain political leader and only allow negative posts about an opponent, then I'm sure that will have a lasting effect. People can write just about anything they want on Facebook, but Facebook is the one choose to to actually show in our feeds.
