Every week it seems there's another reason to worry that your online life isn't yours, and that what you do online is really just fodder for the Great Marketer In The Sky. Take a recent study by Nielsen, the folks best known for rating TV and radio programming, but who also have a sizable interest in measuring online behavior.
The study made a few headlines because of its findings about class distinctions: Facebook users are mostly upscale, while MySpace users are, well, not, Nielsen says, for example. And Facebookers are much more likely than MySpacers to use LinkedIn, the social networking tool for businesses and professionals.
In a lot ways, the big picture isn't that surprising: people with money who live in urban areas spend more time tweeting and blogging. Any Starbucks barista could tell you that. But just as interesting is the degree to which Nielsen breaks everything down to reveal behavior patterns.
Bloggers and tweeters tend to live in more urban areas, Nielsen says. (They named "New York, Los Angeles, San Francisco, and Chicago," just in case anyone had any doubts. We'll assume the Twin Cities are part of that category.)
