He, just want to ask if there is any service which takes on RSS feed, filter it and create new one. I mean automatically. So i can use this second service feed URL.

(aim is to filter out only posts that contains certian words which interests me)

thanks

Update:
It appears http://feedsifter.com/ and http://www.feedrinse.com/ does it and there are a few more ways http://readwrite.com/2008/03/04/6_wa...your_rss_feeds (appears its called RSS feed filtering too)
