I wouldn’t want to presume to have thought of something before Tim O’Reilly (cf. http://www.guardian.co.uk/technology/2011/mar/15/sxsw-2011-internet-online# ; http://radar.oreilly.com/2009/03/radar-roundup-sensors.html ; http://www.web2summit.com/web2009/public/schedule/detail/10194), but in 2007 I wrote about Web3. I called it mesh networks and widely distributed databases (http://my-world.typepad.com/rworld/2007/09/global-justice-.html http://my-world.typepad.com/rworld/2007/10/more-on-the-mes.html) and cited Dust Network’s (http://www.dustnetworks.com/) sensors as part of the puzzle. Semantic language technologies are part of it, of course, but the ubiquitous mesh, and widely distributed data is what, now, is transforming the world.
For me the challenge is how to humanise this phase of Internet technology development.
