Its not really surprising. Washington is a one trick pony. If you are there, you are in the business of Government; they won't even let you in the city unless you know a few hundred people. New York has far more industries: Finance, Law, Fashion, Publishing-- its perfectly reasonable for a well connected person to exist in one sector and never have any contact with someone from another.

Wow, 43 and Newark is 35th. I would've thought the opposite. On twitter Newark beats JC but no on facebook. Oh well, this is just an interesting fact with no consequences. Some of those cities i would have never guessed.

Top 100 Socially Networked Cities in the U.S.

Anyone who wants to rank socially networked cities is going to be in for a fight. But the brave souls at Men?sHealth aren?t shying away from a tussle, placing the top 100 most socially networked cities in order for all to see.

How did they do it? It appears to be a fair and scientifically valid procedure. First, Men?sHealth figured out each city?s LinkedIn and Facebook users per capita, and then tapped the NetProspex marketing database to figure out each location?s amount of overall Twitter usage.

Not stopping there, the next step was to consult online ad network Chitika to quantify traffic from MySpace, Friendster, Reddit and Digg, and finally, SimplyMap helped determine the percentage of households using chat rooms and blogs.

The list below is as much a study of how to find this information as it is a valid assessment of which city has the bragging rights to calling itself The Capital of Social Networking. Speaking of capital, who knew our nation?s capital, Washington, D.C., would be at the top of the list, or that Milwaukee (#45), the location of Mashable?s humble Midwest Test Facility, would rate higher than the mighty New York City (#53), home of Mashable HQ?

See how your city ranks, and feel free to trash-talk those other lesser bergs in the comments.
