4. Twitter: Friends, Followers, and Setwise Operations

Chapter 4. Twitter: Friends, Followers, and Setwise Operations

Unless you’ve been cryogenically frozen for the past couple of years, you’ve no doubt heard of Twitter—a microblogging service that can be used to broadcast short (maximum 140 characters) status updates. Whether you love it, hate it, or are indifferent, it’s undeniable that Twitter has reshaped the way people communicate on the Web. This chapter makes a modest attempt to introduce some rudimentary analytic functions that you can implement by taking advantage of the Twitter APIs to answer a number of interesting questions, such as:

  • How many friends/followers do I have?

  • Who am I following that is not following me back?

  • Who is following me that I am not following back?
