Search engines have evolved significantly over the past year, to the point where you can now run a search at Google or Yahoo!, and generate an RSS feed for that particular search. In fact, there are a lot of sites that will generate RSS feeds for your search. But what a pain it is to go to each site to run your search and get an RSS feed.
Let Tara Calishain and her fabulous new Kebberfegg tool do all the heavy lifting for you. Just enter your search query, and choose a category of RSS feeds you'd like to search (you can choose multiple categories). Kebberfegg (it's a mushed up word for "Keyword-based RSS feed Generator") will provide you with a list of feeds for that search -- you can see it in HTML, or get the list as an OPML file that you can easily import into your newsreader.
Seriously cool tool.
