Remember Yahoo Pipes? It was a terrific web-based tool for pulling in data feeds, manipulating, combining, and filtering, and then generating a new feed with the results. Like anything useful, Yahoo killed it. Now there is Pipes.digital as a replacement. I wish there was more info on how this will be supported and maintained, or even who is running it. But it's a nice looking option right now so I'll be keeping an eye on it to see what it becomes.
