Using Reddit to Help Me Decide on a Topic

I submitted the question of what my paper topic should be to reddit.com. Lets see what The People think. Here is the post:
So I am taking a class on Business and Social media, I can have the professor assign me a topic or I can suggest my own. So, since social media is a dialog, I thought I would elicit some feedback. So, dear redditors if you were taking such a class, what would you write your paper on? Some broad areas I was considering:

• User tools for social services
  
• White hat social media marekting
  
• Black hat social media marketing -Monetization strategies for social media
  
• The long tail of social networking
