"Mash-ups are called Web 2.0, but they are data integrations - taking a piece of display technology like a map application and doing a handcrafted data integration. I’ve yet to see a mash-up that uses semantic Web data and crafts it - the fact that everyone has their own mash-up tells the story.

"What I’ve always wanted to do is take an arbitrary thing, a data file, and if it’s got something that can be mapped, drop it into a map and see what occurs without programming."
