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.
