If you’re online, the chances are 1 in 5 that you’re updating your Twitter or Facebook status, according to a new study by the Pew Internet and American Life Project. And if you’re a female African-American college graduate making less than $30,000 a year and hauling around a mobile device, the study says you’re probably tweeting more than anyone else.
The report is another indication of how researchers are trying to figure out who you are and what you’re doing on social media. (The other day I took a look at a new Nielsen study that shoe-horned Americans into one of 66 demographic segments and then described how they use social networking sites. Major trends: Facebookers are more upscale than MySpacers; bloggers are more urban than rural.)
