Kebberfegg is a tool to help you generate large sets of keyword-based RSS feeds at one time. Keyword-based RSS feeds (some people call them "search based feeds") are those RSS feeds generated as a result of doing a search -- for example, both Yahoo News and Google News have keyword-based RSS feeds.
Keyword-based feeds are great because they can save you a lot of time by automatically updating search results and sending them to your RSS feed reader. But it can take a lot of time to set up all the keyword-based feeds you might want to use across several different resources. Kebberfegg gives you one place to set up as many as three dozen keyword-based RSS feeds at a time, in yummy HTML or OPML flavors
