I rather like this little graphic from [Ross Mayfield,](http://ross.typepad.com/blog/2009/10/web-20-square.html) based on ideas being discussed at this year’s [Web 2.0 Expo](http://www.web2summit.com/web2009/public/schedule/detail/10194). You can download the supporting report [Web Squared: Web 2.0 Five Years On](http://assets.en.oreilly.com/1/event/28/web2009_websquared-whitepaper.pdf).I think it neatly encapsulated the four issues that will effect the web, and which the publishing business needs to get its head around. I talk a lot about social on here, and the whole hyper-local journalism movement is, to some degree, predicated on the idea of geo-centric technology, even if the potential benefits of geocoding information haven’t really been discussed.
The whole mobile environment has been changed by the new breed of smart phones, led by the iPhone, which are turning users into voracious data consumers on the move, and the Real Time web is becoming, in a technological sense, a very real proposition (and, if fact, I should write a post about that).
This graphic is the sort of thing every publisher and journalist should be looking at and thinking “what does this mean for what I do?”
