Modacta can process and RSS feeds (Really Simple Syndication)

It can also find out if a website you know of has a feed available.

The easiest way to see of a website has a feed is just to type in the url.

If there is a feed available it will pop up and you can add the source.

If nothing pops up go to the url right click then click view source. Then do a find and search for "rss" or "feed"

Not all websites have RSS feeds but most do.
