Part of a lesson for the Stanford Journalism Computational Methods in the Civic Sphere
This is a short tutorial on how to use command-line tools, including csvfix and t, the command-line Twitter interface, to access and parse data from the Sunlight Foundation and Twitter. The end goal of this exercise is to gather who everyone in Congress follows (friends, in the parlance of Twitter), and then count up the common friends to find out which Twitter accounts are most followed by members of Congress.
Here's a screenshot of the result, after it's been imported into [Google Spreadsheets](https://docs.google.com/spreadsheets/d/1cjRJyrPYj8KAhUrot8ubPOWgbAwm0OqIgPtsswJ2sjM/edit#gid=1358907576

Basecamp's new book Shape Up is now available online (https://basecamp.com/shapeup) to read page-by-page.
There is a .pdf
version, but that's not the best format for Kindle / other eReaders. Instead, we can convert the page-by-page into an eReader friendly format.
NOTE: This has only been tested on Chrome
