 This class has a single attribute, `site`.
 When we finish writing our ETL CLI, we will be able to pass in different contexts at runtime:
 
 ```bash
-etl-cli +context=[]  # use default wikipedia
+etl-cli +context=[]  # use default hacker news
 etl-cli +context=["http://lobste.rs"]  # query lobste.rs instead
 ```
