Write up

1.  Choose an online reputation system (other then Yelp).  Hypothetically, let's say you choose Amazon.  Discuss motivations for leaving feedback.  What is the cost of doing so?  What does one gain by doing so?  Discuss the costs of leaving deceitful feedback.  Is there a punishment mechanism in the system?  What do we know about the rater of the feedback - their reputation?   Please show examples of ratings and comments from items in the reputation system.

2.  Look at the review for a movie on Rottentomatoes.com.  For example:  http://www.rottentomatoes.com/m/rush_2013/
The site has reviews from expert critics and the general audience.  How do the reviews and ratings differ?  Are the reviews aimed at the intended audience?

Responses should be submitted via compass in PDF form.
