If you have played in Apple’s terminal, or any other *NIX system the chances are there that you have done some piping with your commands. Remember: || … Now Yahoo! offers a service they have called Pipes: Allowing you to pipe various commands and services together.
I really like the direction this service seems to be taking, and will be following its success. TechCrunch has more: Yahoo! Launches Pipes. Pipes worked well in FireFox, but almost choked up Internet Explorer completely.
