BlastCasta users can aggregate feeds together, filter, and sort them quickly using the BlastCasta Feed Engine. They can then use the resulting feed in any way they want, including with other BlastCasta services such as the BlastCasta Add News Wizard that allows the creation of news and other content widgets from feeds.
In addition to combining and filtering feeds, BlastCasta offers the ability to sort items, to translate feeds between many languages, suppress images, remove HTML tags, convert between RSS and Atom, and has advanced filtering options.
