In the modern world, it is difficult not to get information at all, but rather to filter out what is unnecessary, so as not to waste a lot of time. I myself prefer to use RSS to get all kinds of news, rather than visiting websites, and that's why Yahoo's attempt to create a tool for the visual construction of data processing systems appeals to me.
Yahoo Pipes can be used in many cases, for example, you can just choke on messages from some very active source, but you are only interested in those that relate to some special topic. Or vice versa — you would like to delay all messages on some topic leaving all the others untouched.You can also use Pipes to collect information about a topic or resource. In particular, I was interested in the mention of our site in the Russian-speaking blogosphere, as well as how the resource looks from Yahoo's point of view. It would be logical to get one feed, not several, besides, I know that I will still configure and debug it, and it is better to put the filter after combining all the sources.
This is, if not the simplest example, then one of them. What is particularly pleasing about creating — everything is interactive, you immediately see how your actions affect the result.
You can search through a giant catalog of ready-made solutions or create your own, taking an existing one as a basis, or «from scratch ». In particular, try to look for yourself.
But the possibilities don't end with filtering and merging at all. You can really dig into the feed's message structure and build your own. Try.
