So we read lots and lots of tech headlines at this show. Facebook’s after Foursquare’s market; Apple’s after Microsoft; Google’s after everyone—the constant maneuvering and strategizing feels sometimes like a giant game of Risk. Now it is, literally.

This map belongs to the folks at Web 2.0 Summit, an invitation-only conference on the Internet economy. Even to them, it can be hard to see the big picture with so many players jostling for position. As Web 2.0 blogger John Battelle puts it:

The narrative is so rich, it struck us that it lends itself to a visualization – a map outlining these points of control, replete with incumbents and insurgents – those companies who hold great swaths of strategic territory, and those who are attempting to gain ground, whether they be startups or large companies moving into new ground.

You can make comments on the map, and pretty soon, the mapmakers promise, you’ll be able to play the game. Let’s hope the rules are not too complicated.
