Why i'm doing this

I have an upcoming assignment about networks, internet lans etc. For this I have decided to show how not secure the internet actually is. Not because of Security protocol or weak encryption but because people are idiots. People are stupid, and I want to try and prove it. First step is to see how much personal information I can get about three of my friends, without even adding them on Facebook. Now I will try to see how much personal information I can get. Wish me luck
