The BBC has a new site called The Feed Factory . It is an introduction to the RSS feeds that are available from bbc.co.uk. It also includes a very good introduction to RSS for those new to the technology, and for experienced users, it takes you to a directory which organizes their RSS feeds by category. In addition any page on the BBC that has an RSS feed also has the familiar orange RSS icon 
along with a link to the the feed.
