THE HEADLINES: Four feeds were used on Yahoo! Pipes:  World News, Top News, and two columnists’s feeds, those of Christopher Dickey and Fareed Zakaria.  The RSS feeds appeared to return few of the stories that came through the same keyword search on Newsweek’s website, whether there was minimal news on the topic for which the search was conducted (i.e. “Sudan”) or more extensive coverage on the search term (i.e. “Iraq”).  In part that might have been because of the problems in the website search that appeared to rank by relevance (although even that wasn’t clear) rather than by date, so it was difficult to determine by scrolling through the first dozen pages of the website search returns whether the results were the same.
