Just in time for a presentation about widgets, I’ve finally figured out Pipes. It’s pretty cool – it can make portable RSS displays and it can also sift through data. The interface is a lot of fun to use — pull modules and stack them together. Popfly works much the same way, but a lot of stuff seems to be broken, like it doesn’t work in most of my browsers and I can’t get the license keys I need to add Yahoo blocks to any mashups I create. Has any one had better luck? I’ve also had a lot of fun with Sprout Builder.
