Pipes is a powerful composition tool to aggregate, manipulate, and mashup content from around the web.
According to the homepage of Yahoo Pipes - this is what you’re going to be able to do - easily. For those who are unfamiliar with the terms of “aggregate” and “mashup” in the context of the web, in plain English, it means that you can use Pipes to collect sources of news or information from diverse sources and manage how that information is displayed back to you. You can sort and filter information this way, further tailoring it to your needs or wishes, which you can then re-share with others using a badge.
