Is the Internet Conscious?

I've been reading on some Aritificial Intelligence stuff lately, and was thinking about how the brain is a series of neurons, each firing in response to stimuli. Each individual neuron doesn't really have an idea of what the other neurons are, or what they are doing. Then I began to wonder if the Internet works in the same way. All the users are the millions of neurons, and work independently. But when taken together as whole, is the Internet like a big brain? And if so, is it conscious?
