Satoshi,

Interesting post ... a few questions without reading the article. How is the percentage at the bottom of the histogram calculated? Is it a ratio of # of internet users in the state who utilize the internet for political purposes to the # of total internet users in the state? Or is it simply a ratio of total internet users to total state population? I'm sure the article explains, but I have not yet looked at it. Additionally, it would be interesting to see what sort of error is applicable to the data collection, what the sample size looked like, etc. I wonder if there is a correlation between these percentages and per capita personal income by state (http://www.infoplease.com/ipa/A0104652.html), whether or not a large percentage of a state's businesses belong to the high-tech sector, etc.?

Thank you for the feedback, Kyle.

It is it simply a ratio of total internet users to total state population.

Regarding the confidence interval, the paper has "90% fonfidence interval" at the end of paper (Appending Table 3). For example, in case of Alabama, the range is 50.5% to 55.8%.
