Don't most blogs tend to be read by people in that country though? Perhaps there are subtle cultural differences in topics, language, style that make blogs more appealing to people who are culturally similar... for example, I know that Dell concentrates sales forces by geography to some extent, so that when you call from the South you get another person from the South and might be able to chit-chat about whatever Southerners like to talk about (mint juleps?)
