Comscore Media Metrix have come up some fascinating demographic data about Twitter users. 18-24 year olds are 12% less likely than average to visit Twitter (Index of 88). It is the 25-34 year olds and 45-54 year olds who are really the ones driving its use (i.e. this older group are 36% more likely than average to visit Twitter). Interesting to see the oldest groups are not your usual techno-laggards. Maybe older people have more to talk about? Our personal experience, as a Charlotte marketing agency and Charlotte ad agency: the people using twitter are the ideal age for a smart B2B social media strategy.
