Week 5	February 28	Midterm
Week 5	March 1	CLASS CANCELLED - Professor at a conference		Read Chapter 7 of Blown to Bits As you are reading, consider these questions: Why is DOPA controversial? As a teen, did you face monitoring or censorship by your parents? Did they let you watch R-rated movies? Listen to music with explicit lyrics? Did they let you have a cell phone? A car? Did you have your own computer, or use a shared family computer? Did they monitor your internet usage, and/or run a site blocker to stop you or siblings from viewing inappropriate materials online? Should sites like MySpace, Facebook, etc. be totally uncensored, or should they allow any content whatsoever to be posted and transmitted? What content (if any) should be forbidden? (hate speech, defamation, profanity, pornography, child pornography, drug trafficking?) What, if anything, should sites like MySpace, Facebook, Twitter, etc. do about the problem of sexual predators and other crime that may be facilitated by their services? Are they at all liable for such events if they occur? (Are they more like a distributor/truck, a newspaper/publisher, or a library?)
