RssMecano.com : Moteur d'extraction de flux RSS à partir d& Terraminds twitter search. Why RSS Search Feeds Based On Web Searches Are Important - Robin. Of course, if you want to monitor the news, and only those sources that have been accepted by Google, MSN and Yahoo as approved news sources (quite a limited number), then I have no problem in agreeing with the above.
But say that relevant sources that have highly valuable content on the topics you care about are not part of that pool of a few thousand sources that Google News and its competitors monitor on a hourly basis, then you are both under-served and left out of a great deal of very useful stuff. For example, assume that you want to monitor what is being said about new RSS tools and technologies or even better about the very topic we are talking about: RSS web-based search feeds. RSS search feeds tapping into Google News, Yahoo News and MSN can surely bring up a constant stream of interesting things. Are you getting the latest from Scoble, Winer or me when you search there?
