Yahoo Pipes I am way behind on using yahoo pipes, but after playing with it for a week now and learning just how it works I am having a lot of fun. It's a pretty powerful little tool that has a great interface. The great thing is, the actual tutorials for yahoo pipes, are patterns of pipes themselves that you can play with. For example, if I wanted to combine my own blogs rss feed with some search results from twitter, then I can do it in this interface.
– To go along with this there is JSPlumb, which helps you to link thinks together just like Yahoo Pipes does.
