Yahoo is doing something interesting, called "Pipes". This web page describes the concept of Pipes nicely and how they might be used to connect disparate pieces of information together.

The idea behind Yahoo Pipes is to allow users to create their "mash-ups" easily. A mash-up is simply two or more pieces of information put together in a way the original authors did not imagine. A web example includes Google Maps with New York City Pubs, allowing you to see the pubs of New York on a Google Map. Musicians create mash-ups by taking two pieces of music and creating a third out of it (while hopefully adding something unique in the process).

The idea of having lots of information sources available (as is currently the case on the web) and having these information sources easily combined to create new insight is rather interesting. As the article above discusses, complex organisms are often described as incredibly intricate networks of simple pieces of information (e.g. a brain is just a huge network of neurons). We now have the information "neurons" in the current Internet, so the next race is to connect them in meaningful ways...
