Cheating in school has increased in the past 50 years or so according to surveys. Also, I talk to people on facebook that I wouldn't hang out with or even see in real life. I met them once somewhere friended them and now we can talk about stuff, which might lead to me hanging out with them. Usually when you meet a person through a friend you don't hang out with them without that friend around. Stuff like facebook and myspace change that(although I am against blogging)
