I just was reading about a neat little online gizmo called "Pipes" from Yahoo.
Basically a mashup tool that lets you wire different types of feeds into some canned library modules to sort/modify/display and re-aggregate data.
You can publish your Pipes with a unique URL.
You have to have a Yahoo account to use but it looks like it has a cool visual editor.
Seems kind of neat, I will have to play around with it when I get a chance...
