For the first year, we created the map. For the second, we updated it with a Simcity-like data layer.The Web 2.0 Summit 2010 Points of Control map. So fun - and so well received - that we were invited to help improve it for 2011 by adding yet another layer of data. Literally. A Data Layer.This year's addition shows the major web and 2.0 properties in terms of data access - what data makes them tick, and how powerful can they become. Sam's meticulously drawn cities show the relative amount of data each organization collects, and you're always just one layer away from bringing up last year's map.Another year, another map? We like to think it's another opportunity to do something fun.
