There are tools available that let you do some extra things with RSS feeds.
Display feeds on your website
Mix RSS feeds
You can combine items from a bunch of RSS feeds into one unique list. This can be useful if for example, you get news stories from a few different places and you want one big list of news stories. The website rssmix.com can perform this service for you.
RSS by email
You don't necessarily need an RSS reader to read feeds, you can get them by email! The website feedmyinbox.com can perform this service for you.
