Saw this introduction on Yahoo Pipes and decided to try it out.

A mashup is created from a GUI that one can drag and drop components to construct the logic (aka programming...).

Yahoo Pipes creation

A user can select the source of data, perform processing to data source, and display result.

Components can classified into 3 types:
Input - various data sources like RSS feed, Google base, CSV, user input, and etc.
Processing - There are filter, sorter, and various of data processing to massage the in-coming data.
Output - where results are show on the web

A result of the pipe is display in a page, which can be subscribe as RSS feed itself. A pipes can also be published to allow sharing with others.

Yahoo Pipes output

I have not spend too much time on it but wondering how powerful this tool is, and yet to figure out how to do more complicated processing:
- Get the contents of each item in a feed, and extract all links and display it.
- Get each item from a feed and search and display all links to it.

Maybe I will try some more later to how to do these.
