The newsfeeds that i worked with 

feeds = [

    {"url":"http://www.nytimes.com/services/xml/rss/nyt/GlobalHome.xml", "name":"New York Times", "location":"America", "timezone":2},

    {"url":"http://feeds.guardian.co.uk/the guardian/rss", "name":"Guardian", "location":"England", "timezone":2}

# pickle the db...
