6/30 Electronic tattoos

Hey guys

Sry for late post the disscussion material this week~

Plz see the following TED video:Big Data, Tattoos & Immortality
http://www.ted.com/talks/juan_enriquez_how_to_think_about_digital_tattoos.html

Here are some questions I want us to talk about:

1.)Do you think that its normal to Google a stranger before meeting them in person? Why or Why not?

2.) American government spied on millions of Americans’ phone records and on the internet activity of hundreds of millions of foreigners to protect its citizens, do you think it's decent?

ps:Compare with the internet firewall & cencorship in China.

3.)How do you think about put anything on Facebook or twitter...what kind of informtion you think is not proper to share online?

4.)Keep 100% anonymity online also brings lots of problems, agree or disagree?
