The script grabs the domain of the uri in question, so it's effectively mapping the domain to the url. To answer your question more specifically, the freedom.txt format started in this thread: http://news.ycombinator.com/item?id=3498505 http://news.ycombinator.com/item?id=3498505 , so it links to the uri of a freedom.txt for historical reasons. /etc/hosts integration is in the works; you're the 2nd person to recommend it so far (the first being my roommate ;-) ). What's up now is just a quick hack to get momentum for the project in the meantime. If this takes off, the innovation will be social rather than technical, so I thought I'd spend 5 minutes to see if it's worthwhile. Thanks for the input! Edit: I'm working on /etc/hosts integration right now.
