The University of Buffalo is undertaking a long term project that will geo-code the blogosphere.
Huh?

What they will be looking at is blog trends in the US.

…how information from blogs produced in specific American urban areas reflects the political agendas, opinions, attitudes and cultural idiosyncrasies of the general population of those places.

They are seeing what Pew Research and others are seeing, concentrations of blogs in certain urban areas.

* American blog distribution correlates positively with the distribution of the U.S. population, with most bloggers heavily concentrated in large cities in coastal areas and their surrounding suburbs (New York; Boston; Los Angeles; Chicago; San Francisco; Washington, D.C., and Philadelphia)

* New-technology and economic centers and clusters have formed large groups of bloggers. Among them are the San Francisco Bay area; Austin; Houston; Atlanta; Orange County, Calif.; the region east of Phoenix (Mesa, Chandler and Tempe); Las Vegas, and Portland

* Suburbs and regions surrounding big cities such as Detroit; Washington, D.C.; San Francisco; Boston; Phoenix; Los Angeles; Dallas, and Seattle have blogger groups comparable in size to those of their center cities.

* There are very few blog concentrations in the inland U.S., particularly the Midwest.

They also concluded that the densest concentration of bloggers is found in areas traditionally associated with “culture elites” and high socioeconomic status:

* Average household incomes in most of the 26 three-digit zip code units in which the majority of blog-clusters are found are, at around $59,000, higher than the national average and in six of those 26 areas, average household income is more than $100,000.

* Some concentrations of bloggers were found in cities where household incomes are relatively low, but those were either college towns like Berkeley, Calif.; Bloomington, Ind.; Madison, Wis., and Tallahassee, Fla., or cities like Austin, Texas; Orlando, Fla.; Atlanta and Worcester, Mass., in which 18-34-year-olds make up more than 25 percent of the population.
