The goal here is to be able to create a webapp that will load an RSS feed, allow the user to make in-line changes to it through fun AJAX-y controls and postbacks, and then save / host the edited RSS feed.
The motivation for this project came from observing that many of the UC Berkeley webcasts had fun titles like "Lecture 34" rather than the actual topic that was covered, so I want to edit and save custom versions of feeds for classes I'm interested in.
