OECD is currently exploring new systems for visualising statistics and allowing users to to launch substantive online discussions based on them. See the OECD Factbook on Swivel for an example of how this might work.
Being a real lover of visualisation - give me a chart any day rather than a page of figures - I had to go and look at this. Swivel is "in preview" (I'd be more likely to call it "beta") and to find the OECD Factbook you have to use the search function. That said, however, the data looks stunning!
