I have played around with Fyuze.com today, thanks for the link Dave. The site is in beta but it allows you to build searches queries along with subscribing to rss feeds. I was disappointed that the service did not have more blog search engines tied to it. I would have liked to put in the query "geek news central" and had it spill out a rss feed that was made up of searches from Technorati, Icerocket, Pubsub and Feedster all together but this is not the case.

Fyuze lays your queries out in boxes sadly no combined RSS feeds but it is a good start will have to keep my eye on this site and see how evolves. [Fyuze.com]
