At yesterday’s panel here about user-generated content, I quoted Dave Winer’s comment on my blog post about the last such panel I’d attended, at Davos: Here’s a panel with no users generating content. This, I said, was symbolic of the state of the discussion: All the big, old guys still act like closed products, not open networks. I asked whether they could. In the discussion that followed, one of the panelists asked Chris Ahearn of Reuters whether they were ready to open up their source material. He said they did. No, said the fellow panelist: giving people source documents so they can remix and report and find more. Ahearn said he’d ask his editor. I liked that exchange.
