If you dont already know about it, you may find dbagg3 from Leslie Orchard interesting too. Right now it seems like “yet another aggregator”, but from what he outlined in his early posts about dbagg3, the aggregating feature is only one of many, and easy searching/processing of Atom feeds/entries is another. You can find Leslie’s latest post about dbagg3 at http://www.decafbad.com/blog/2004/09/13/dbagg3alive
