Rafat Ali asked Jim Kennedy for more details on the AP's intent with RSS feeds--as in, are they trying to create a news portal (The answer is no.) Jim responded(in part):
"It's an experiment right now to explore the impact on traffic to the news pages we host for member newspapers and broadcasters. We have a service called Custom News, which provides hosted national and international news pages for hundreds of member sites. These RSS feeds click through to those pages.
If a user picks up one of the feeds from a member site, clickthroughs will always go to that member's version of the hosted pages. "
