RSS feeds

My workplace intranet Homepage uses portal technology which users can customize to include portlets with news feeds. Each person must customize his/her portal to include a portlet for each newsfeed that s/he wants. I set up two of them for myself: Science Now and Dialog's database Bluesheets.   I have been reading them for a few months now.  I also tried and like the feed from Science News, but it's similar to Science Now, so I do not subscribe to both of them.  I am not sure how many employees here have actually used the RSS feed portlets on their personal portals.
