How about converting the news feeds into a keyword cloud? I did some research and this is already being done for quite sometime. The notable entries are
fserb.com.br/newscloud/ which creates a news cloud out of Google News.
newzingo.com is another site that’s doing news cloud not only for Goolge News, but also other sites like Slashdot.
tocloud.com also uses Google News to create the news cloud. However, only phrases are presented. The advantage with a cloud made of phrases as compared to keywords is, that the phrases give more context. This is especially important for a text source like news that keeps continuously changing and a keyword’s importance is very temporal.
