4. Easy Communication
Remember when you had to take the time to call your friend or go over to their house to talk to them about something. Well that is simply not an issue anymore. Texting, instant messaging, and social networking have made this communication problem non-existent. Which leads us to the downside; we can contact anyone and set up any kind of event. Want to have a house party with some friends, well dont tweet it because you may be getting more than you bargained for when half the city and then some shows up. And Im not even going to get started on how this helps terrorists.
