The Role of RSS in Science Publishing:
Syndication and Annotation on the Web

NPG’s interests in RSS extend well beyond the production of RSS feeds. A new server-side application that has been developed by NPG is Urchin [35]—an open-source aggregator designed to aggregate and filter RSS feeds and other data sources.

I find the filtering ability interesting, if the software can learn which articles are interesting to me and separate them from the others, it would markedly increase the efficency of the information gathering and my ability to keep aware of those areas.
