When website managers first discovered RSS, back in 2003 or so, feeds were often published like this:
That’s from the Canucks site. They list these two feeds on their RSS page, with no explanation of what each one contains. Which feed do I want? Is one the subset of another? Does the result of each game qualify as a ‘top story’ or plain old ‘news’?
I was guilty of something similar in 2003, when I still worked for the Man. I don’t think we were very thoughtful about how we split up our news (we had a press release feed and a corporate news feed or some bollocks).
But we’ve had five years to learn, and it’s not brain surgery. Provide one feed with everything in it, and then slice out a few feeds in ways that people might actually want to use them: game highlights, off-ice team news, corporate updates, and so forth.

afaik drupal and other modern web site building tools like wordpress allows you to generate one rss feed per tag and slice and combine them
don’t use a tool which doesn’t let you do that! it’s 2008!
