You could be forgiven for thinking Twitter was the latest example of youth culture.
From the ability to fire off grammatically-abbreviated updates about daily trifles to keeping tabs on celebrities, the fast-growing microblogging service has all the earmarks of a young person’s pastime.
But Twitter devotees are grayer than one might expect: The majority of Twitter’s roughly 10 million unique Web site visitors worldwide in February were 35 years old or older, according to comScore.
In the U.S, 10 percent of Twitter users were between 55 and 64, nearly the same amount of users as those between 18 and 24, which accounted for 10.6 percent of the total.
Twitter has seen its popularity explode in recent months, with the number of unique visitors to its site increasing by more than 1000 percent year-over-year in February, according to comScore.
