1) No you need to re-implement the parse_feeds function so that it scan the page
http://www.theatlantic.com/doc/current and returns a list of the form
Code:
[('Title', 'URL'), ('Title2', 'URL2'), ...]
Each URL will be of the form "http://www.theatlantic.com/" + the contents of the href attribute.
You can use the BeautifulSoup class to easily parse the HTML
