Instead of a blog post this week, here are a few interesting items worth reading:

• James Altaur’s Quora post discussing the psychological techniques used by Eminem to win a rap battle in the movie “8 Mile.”
• Shea Sorrano’s post on Grantland discussing the greatest rap song guest verses of all time.
• Nate Silver creating an interactive chart for FiveThirtyEight about US flights, tracking which airports and routes are the fastest.

Enjoy!
