Feedshake allows you to enter a pile of other RSS feeds to create a single customized feed.

I wanted to create a feed to track all of the people and topics in my shitlist. I started by going to Yahoo! News and doing a search for the person or topic. When the search results are kicked out, you will notice the Add To My Yahoo and orange RSS buttons down a bit in the right hand column. Thats pretty cool by itself.

I did several searches to create the parameterized RSS urls for each of the idiots/topics in my shitlist, then plugged them into Feedshake.

The resulting Shitlist Feed surprised and delighted me. I love truly customized information.

I also have to give Feedshake kudos for their idiot-proof sign-up process. It let me start the process of creating the feed before presenting me with a wonderfully simple combo log in or sign up with an email address and password.
