I have spent some time browsing Yahoo! Pipes and I have to say that it’s nerdy cool – so nerdy that it’s cool if you are into geeky things in the RSS world. First things first, this is not the type of application that your average web user could use. It is, however, the type of application that the average web developer (or mashup developer) could utilize very quickly and easily. I am surprised that nobody has done more to release a service like this before – it seems natural to remix RSS feeds and integrate more web content to make it more useful and interesting. I’ll be curious to see the kinds of pipes that people create. I particularly like this one, which mashes up the New York Times and photos from Flickr.
