Fred's distinction between algorithms and human aggregation is exactly what has motivated me over the years to create Clipmarks.com and now Amplify.com. Different people can see the same thing in so many different ways depending on their perspective. Algorithms don't have perspective, they don't have experience and they don't have heart. So as amazed as i am by what algorithms can do, i'll always be more amazed and interested in what people can do.

Good insight! I'm going to be thinking on this for a while! Thanks.
