Roll Your Own RSS
You use the BBC search engine to find the content you’re interested in and then subscribe to the search results. This is a clever way to subscribe to a very specific subject, rather than the more generic BBC News or BBC Sports feeds that are offered.
I would like to see this feature offered on other web sites. Some RSS feeds I subscribe to cover a very broad spectrum of news where I might only be interested in certain subject areas.
The ability to fine tune an RSS feed would be an asset on any web site where a large quantity of content is published. I could see people liking this.
