"The GPS looks forward for me, projecting all my future successes and failings. Every bit of information helps to optimise my path. Contour maps spring out of the hills surrounding, and round the corner ahead. It took a space shuttle and an army of volunteers to help me shift down a gear, and hopefully the data exhaust I leave behind will help someone do it better next time." Tom is brilliant. I miss him.

"The point here, is that the flickr team did not wake up one morning and think: “You know, if we captured THIS kind of data, we could create this mashup; so let’s create an application.” Instead, they re-used data they were already capturing, and brought out something very interesting indeed. By creating tools which match their data (and could be used with other data of the same kinds), flickr is able to expose layers of value from the rich-pickings of their own data-cloud. The good stuff is where the data are." Yes, it is.
