A few weeks ago my Digg Yahoo pipe broke. It's now fixed. The user (you know who you are) can once again enjoy all-that-is-popular on Digg from the comfort of his Google Reader.
Technical Note: Once again the breakage was the result of some changes Digg made. This time they changed their RSS feed so that it doesn't contain a bunch of important information like the direct link to the article. They also appear to have blocked yahoo pipes access to their APIs.
Yahoo Pipes: Strange thing about Yahoo Pipes... It hasn't changed a lick since the day it was released. It had so much promise. With a little effort they could have a thriving developer community and could be making a fortune off adertising and value add services. But they just neglect it. It boggles the mind.
