Using Pipes seriously
There are, I think, two main reasons for not using Yahoo! Pipes as a basis for tasks where you give out the feed to others: The ugly URL and the dependence on Yahoo.
If I want to do something with the feed of my weblog before I give it out to my readers, I don’t want the readers to subscribe to something like http://pipes.yahoo.com/pipes/pipe.run?_id=0Du9npU43BGDeax_D9XErg&_render=rss. If Yahoo decides to shut down Pipes, which is speculated here, my readers are lost. Also, the URL is ugly.
What I want, is a nice address in my own domain that looks good. And I would not be posting this, if I did not have the answer :)

I use the Wordpress plugin redirection as a solution. Using pass-through, one can add redirections where the URL does not change. I collected all the feeds on an extra feeds page. There are (currently) five feeds, all with addresses like www.rockbüro.de/feeds/… Some of them are built using Pipes, others are not (Even my del.icio.us-Feed can now be subscribed using www.rockbüro.de/feeds/links).
If Yahoo now decides to shut down Pipes, I can replace the Pipes functionality by another service (or, in the worst case scenario, code it myself in one days work) without letting the readers know.
