I was with the author before the lame foursquare plug. I am not going to go to a coffee shop anywhere and ask anybody what foursquare is, because that does not prove anything and I am not going to foursquare's advertising for free. But I am going to make mental note that any blogger that mentions foursquare gratuitously without relevance is a shill and should not be trusted.

I think you missed the point. What the author was trying to show was how different regions adapt new technology.

In my "world" almost no one uses Twitter, 4square or any other new technology/tools. This means starting a new trend and getting early adapters (from within my social circle) is extremely hard.

Twitter could never get started here. FourSquare would of never got enough usage to prove the concept.

IMHO, this is a very important point for social (and many other types) of startups.
