I was there this summer. martinced's comment made me laugh out loud.

For martinced's information, about a third of the population of Argentina lives in the Buenos Aires metropolitan area which has a nice bright dot. Uruguay is not fine, it has almost nothing. I think you're confusing it with Brazil hahaha.

Of all the people I met in Argentina, if they didn't use twitter it was because they had better things to do. They all used facebook for example.

If you're going to glean any political ideology from this map, you should get off this anti-socialism fetish and look over at Africa...
